Complete Guide to Attack Speed in Dota 2
Master attack speed mechanics, calculations, caps, and optimization to maximize your DPS and dominate fights
Attack Speed Overview
What is Attack Speed?
Attack speed determines how quickly your hero attacks. It's one of the two primary factors in physical damage output (the other being attack damage). Understanding attack speed mechanics is essential for optimizing your hero's damage per second (DPS).
Attack speed in Dota 2 is a complex mechanic involving Base Attack Time (BAT), increased attack speed (IAS), and various modifiers. Unlike many games where attack speed is a simple stat, Dota 2 uses a sophisticated formula that requires understanding multiple components.
Why Attack Speed Matters:
- DPS Scaling: Attack speed multiplies your damage output by increasing attacks per second
- On-Hit Effects: More attacks = more procs of bash, critical strike, lifesteal, and other effects
- Farming Efficiency: Faster attacks = faster creep clearing and jungle farming
- Tower Damage: High attack speed dramatically increases building damage output
- Kiting Potential: Fast attacks allow better attack-move patterns and animation canceling
- Synergy with Abilities: Many hero abilities scale with attack speed (Juggernaut, Troll Warlord, etc.)
Attack Speed Formula (Simplified)
Attacks per Second = (100 + IAS) / (100 × BAT)
Where IAS = Increased Attack Speed and BAT = Base Attack Time
Key Concepts to Understand
Base Attack Time (BAT)
The baseline time between attacks, usually 1.7 seconds for most heroes
Increased Attack Speed (IAS)
Bonus attack speed from agility, items, and abilities, expressed as a percentage
Attack Speed Caps
Minimum of 20 IAS and maximum of 700 IAS to prevent extreme values
Agility Bonus
Each point of agility grants 1 increased attack speed
Base Attack Time (BAT)
Base Attack Time Explained
Standard BAT: 1.7 seconds
Base Attack Time (BAT) is the fundamental time between attacks for a hero at 0 increased attack speed. Most heroes have 1.7 BAT, but some heroes have unique BAT values that significantly affect their attack speed scaling.
How BAT Works
BAT represents the baseline attack interval. A hero with 1.7 BAT and 0 IAS would attack once every 1.7 seconds. Lower BAT means faster base attacks, making attack speed items more effective.
Why BAT Matters
- Attack Speed Scaling: Lower BAT means attack speed items are MORE valuable (each point of IAS gives more attacks)
- DPS Baseline: Lower BAT = higher base DPS even without attack speed items
- Item Efficiency: Heroes with low BAT get more value from items like Moon Shard and Hyperstone
- Hero Identity: BAT often defines whether a hero is an attack speed carry or damage carry
Heroes by Base Attack Time
Ultra Low BAT (1.0 - 1.4)
Low BAT (1.5 - 1.69)
Standard BAT (1.7)
Over 100 heroes including Phantom Assassin, Faceless Void, Drow Ranger, Sniper, Luna, and most carries have standard 1.7 BAT.
High BAT (1.8+)
BAT Impact Examples
Same Attack Speed, Different BAT
Let's compare 200 IAS on different heroes:
Anti-Mage (1.35 BAT)
Attacks/sec = (100 + 200) / (100 × 1.35) = 300 / 135
2.22 attacks per second
Standard Hero (1.7 BAT)
Attacks/sec = (100 + 200) / (100 × 1.7) = 300 / 170
1.76 attacks per second
Doom (2.0 BAT)
Attacks/sec = (100 + 200) / (100 × 2.0) = 300 / 200
1.50 attacks per second
With identical 200 IAS, Anti-Mage attacks 48% faster than Doom! This demonstrates why low BAT heroes benefit more from attack speed items.
Increased Attack Speed (IAS) Calculation
Increased Attack Speed (IAS) is the total bonus attack speed your hero has from all sources: agility, items, abilities, and buffs. IAS is expressed as a percentage and directly reduces the time between attacks.
Attack Speed Formula (Detailed)
Attacks per Second Formula
Attacks/Second = (100 + IAS) / (100 × BAT)
Attack Interval Formula
Attack Interval = BAT / (1 + IAS/100)
How IAS is Calculated
Your total IAS is the sum of all attack speed bonuses:
Example: Level 20 Phantom Assassin
Attacks per Second:
(100 + 211) / (100 × 1.7) = 311 / 170 = 1.83 attacks/second
Attack Interval: 1.7 / (1 + 2.11) = 0.546 seconds between attacks
Attack Speed from Different Sources
Agility
1 AGI = 1 IAS
Permanent bonus that scales with hero levels and items. Agility heroes get more naturally.
Items
Varies by Item
Hyperstone (+55), Moon Shard (+140), Assault Cuirass (+30 aura), etc.
Abilities
Hero Specific
Troll Warlord Fervor, Alchemist Chemical Rage, Ursa Overpower, etc.
Buffs/Auras
Varies
Bloodlust (+70 IAS), Troll Warlord Fervor, Ancient Creep auras, etc.
IAS Stacking Examples
Low Attack Speed Build
Early game carry with minimal attack speed:
- Level 10 Agility hero: 60 AGI = 60 IAS
- Power Treads (Agility): +10 IAS
- Total: 70 IAS
1.7 BAT: (100 + 70) / 170 = 1.00 attacks/second
Medium Attack Speed Build
Mid-game carry with some attack speed items:
- Level 18 Agility hero: 85 AGI = 85 IAS
- Power Treads + Yasha: +26 IAS
- Maelstrom: +25 IAS
- Total: 136 IAS
1.7 BAT: (100 + 136) / 170 = 1.39 attacks/second
High Attack Speed Build
Late game carry fully built:
- Level 25 Agility hero: 110 AGI = 110 IAS
- Power Treads + Manta: +36 IAS
- Butterfly: +50 IAS + 35 AGI = 85 IAS
- Moon Shard (consumed): +60 IAS
- Assault Cuirass: +30 IAS
- Total: 321 IAS
1.7 BAT: (100 + 321) / 170 = 2.48 attacks/second
Maximum Attack Speed (700 IAS Cap)
At the cap with 1.7 BAT:
(100 + 700) / 170 = 4.71 attacks/second
Theoretical maximum for standard BAT heroes. Very difficult to reach in practice.
Attack Speed Caps and Limits
Attack Speed Caps
Minimum: 20 IAS • Maximum: 700 IAS
Attack speed is hard-capped between 20 and 700 increased attack speed. Going below 20 or above 700 provides no additional effect.
Understanding the Caps
Minimum Cap: 20 IAS
Even with heavy attack speed slows, your attack speed cannot drop below 20 IAS. This prevents heroes from being completely disabled by slows.
Example: If you have 50 IAS and receive a -100 IAS debuff, you would theoretically have -50 IAS, but the game caps you at 20 IAS minimum.
Attacks/sec (1.7 BAT): (100 + 20) / 170 = 0.71 attacks/second
Maximum Cap: 700 IAS
The maximum increased attack speed is 700. Any bonuses beyond this are wasted. This prevents infinite attack speed scaling.
Example: If you have 600 IAS and gain +200 IAS from a buff, you would theoretically have 800 IAS, but the game caps you at 700 IAS.
Attacks/sec (1.7 BAT): (100 + 700) / 170 = 4.71 attacks/second
Maximum Attacks Per Second by BAT
Reaching the Attack Speed Cap
Reaching 700 IAS is extremely difficult and rarely practical. Here's what you'd need:
Theoretical 700 IAS Build
Even with this extreme build, you're at 656 IAS. Reaching exactly 700 requires even more buffs or AGI items. Most practical builds sit around 250-350 IAS.
When Do You Hit the Cap?
Troll Warlord with Max Fervor
Troll Warlord's Fervor gives up to 120 IAS at max stacks. Combined with attack speed items, Troll can easily reach 400-500 IAS, getting closer to the cap than most heroes.
Alchemist with Chemical Rage
Alchemist gets +90 IAS from max Chemical Rage plus 1.0 BAT. With Moon Shard + Assault Cuirass + AGI items, he can reach 400+ IAS effectively.
Ursa with Overpower
Overpower gives Ursa +500 IAS for 6 attacks. This often hits the 700 cap temporarily, giving him maximum attack speed for a short burst.
Diminishing Returns Near Cap
Once you reach 400-500 IAS, additional attack speed gives diminishing returns. At that point, investing in damage, survivability, or utility items is usually more valuable than more attack speed.
Attack Speed from Agility
Agility is one of the three primary attributes in Dota 2, and it provides passive attack speed in addition to armor and, for agility heroes, damage. Understanding how agility scales attack speed is crucial for item builds and hero progression.
Agility to Attack Speed Conversion
1 Agility = 1 Increased Attack Speed (IAS)
Direct 1:1 conversion - simple and linear scaling
Agility Gain by Hero Type
Agility Heroes
Primary attribute is agility - gain damage AND attack speed from AGI
Examples: Phantom Assassin, Anti-Mage, Terrorblade, Juggernaut, Drow Ranger
Strength/Intelligence Heroes
Agility is secondary - only gain attack speed and armor (no damage)
Examples: Sven, Tiny, Zeus, Invoker (low AGI gain)
Agility Progression Examples
Phantom Assassin (High AGI Gain Hero)
High agility gain heroes naturally reach high attack speed just from leveling up.
Agility Items and Attack Speed Impact
Agility items provide both stats and attack speed for agility heroes, making them extremely efficient:
Butterfly
+35 Agility
+30 Attack Speed
+30 Attack Damage (for AGI heroes)
Total: +65 IAS
One of the best attack speed items, providing massive AGI bonus
Manta Style
+26 Agility
+10 Attack Speed
+26 Attack Damage (for AGI heroes)
Total: +36 IAS
Core item for illusion heroes, good attack speed bonus
Diffusal Blade
+25 Agility
+25 Attack Damage (for AGI heroes)
Total: +25 IAS
Efficient early-game AGI item with mana burn
Yasha
+16 Agility
+15 Attack Speed
+16 Attack Damage (for AGI heroes)
Total: +31 IAS
Early-game attack speed item, builds into Manta/Sange & Yasha
Eye of Skadi
+22 All Attributes
+22 Attack Damage (for AGI heroes)
Total: +22 IAS
Balanced stats item with powerful slow effect
Dragon Lance
+14 Agility
+14 Attack Damage (for AGI heroes)
Total: +14 IAS
Budget range extension item for ranged heroes
Why Agility Matters for Attack Speed
1. Passive Scaling
Unlike items that can be sold or destroyed, agility from leveling provides permanent attack speed that scales throughout the game. A level 25 agility hero has 90-120 IAS just from base stats.
2. Item Efficiency
For agility heroes, agility items provide triple value: attack damage, attack speed, and armor. This makes items like Butterfly incredibly gold-efficient.
3. Synergy with BAT
Agility heroes with low BAT (Anti-Mage 1.35, Juggernaut 1.4, Terrorblade 1.5) get even more value from their natural agility growth, making them exceptional attack speed heroes.
4. Late Game Advantage
Agility heroes scale better into late game because their primary attribute gives both damage AND attack speed. A 6-slotted PA with 150+ agility has massive attack speed without dedicated attack speed items.
Attack Speed Comparison: Agility Hero vs Strength Hero
PA has significantly higher natural attack speed throughout the game just from attribute growth.
Attack Speed Items
Attack speed items are essential for physical damage carries. Different items provide varying amounts of attack speed along with other bonuses like damage, utility, or survivability.

Total IAS: 250-350+
Attack Speed Slows and Debuffs
Attack Speed Slows
Attack speed slows reduce your increased attack speed (IAS), dramatically lowering your DPS. Understanding these mechanics helps you counter enemies and protect yourself from disables.
How Attack Speed Slows Work
Attack speed slows apply negative IAS to your hero. If you have 150 IAS and receive a -100 IAS debuff, you temporarily drop to 50 IAS until the debuff expires.
Major Attack Speed Slows
Untouchable (Enchantress)
-120 to -200 Attack Speed
When attacking Enchantress
One of the strongest attack speed slows in the game. Makes right-clicking Enchantress nearly impossible. Extremely punishing for attack speed carries.
Counter: Magic damage, BKB (blocks the slow), MKB (doesn't counter but helps with accuracy), or simply don't right-click her.
Freezing Field (Crystal Maiden)
-50 Attack Speed
While in AOE
AOE slow that affects all enemies in the area. Combined with movement slow, makes fighting inside the field very difficult.
Counter: BKB, Force Staff/Blink out, stun CM to cancel ultimate.
Enfeeble (Bane)
-60 to -120 Attack Speed
8 seconds
Single-target attack speed reduction. Cripples carries in fights by dramatically reducing their attack speed.
Counter: Dispel (Manta, Lotus Orb), BKB (blocks initial cast).
Crippling Fear (Night Stalker)
-50 Attack Speed
4 seconds (8 seconds at night)
AOE silence that also slows attack speed. Especially powerful at night when duration doubles.
Counter: BKB, Manta Style (dispels silence and slow).
Whirling Axes (Troll Warlord)
-60 Attack Speed
5 seconds (ranged version)
Ranged axes provide blind and attack speed slow. Counters other right-click carries.
Counter: BKB, positioning to avoid axes, MKB for true strike.
Shiva's Guard
-40 Attack Speed
4 seconds (900 AOE)
Active item that slows movement and attack speed in large AOE. Common on intelligence cores and supports.
Counter: BKB, spread out to avoid AOE, dispel.
Rod of Atos
-40 Attack Speed
2 seconds root
Root that also reduces attack speed. Common on intelligence heroes for catch and control.
Counter: BKB, Manta Style, Force Staff.
Eye of Skadi
-20 Attack Speed
3 seconds (refreshes on attack)
Passive slow on attacks. Reduces enemy attack speed and movement speed.
Counter: BKB, kiting, dispel.
Impact of Attack Speed Slows
Example: Carry with Enchantress Untouchable
Before Untouchable:
Carry with 250 IAS and 1.7 BAT
(100 + 250) / 170 = 2.06 attacks/second
~250 damage per hit = 515 DPS
After Untouchable (-150 IAS):
Carry with 100 IAS (250 - 150) and 1.7 BAT
(100 + 100) / 170 = 1.18 attacks/second
~250 damage per hit = 295 DPS
DPS reduced by 43% - nearly half your damage output is gone!
Protecting Against Attack Speed Slows
1. Black King Bar (BKB)
Grants spell immunity, blocking most attack speed slows when activated. Use before engage against heavy attack speed slow lineups.
Note: Some slows pierce spell immunity (check ability specifics).
2. Manta Style / Dispel Items
Manta Style, Lotus Orb, and Eul's Scepter can dispel many attack speed slows. Time dispel to remove debuffs mid-fight.
Best for: AGI carries who can benefit from Manta's stats.
3. Status Resistance
Items and abilities with status resistance reduce the duration of attack speed slows. Satanic active, Aeon Disk, and STR heroes naturally have some resistance.
Effect: 30% status resistance = 30% shorter slow duration.
4. Positioning
Avoid attacking targets with attack speed slow auras (Enchantress, Ancient Dragon). Focus other targets first or use magic damage/spells instead.
Strategy: Let tanky teammates absorb Enchantress attacks while you focus squishier targets.
5. Burst Over DPS
Against heavy attack speed slows, consider damage burst items (Daedalus, Divine Rapier) instead of pure attack speed. Fewer, harder-hitting attacks are less affected by slows.
Example: One 1,000 damage crit is better than five 200 damage attacks if you're heavily slowed.
Attack Speed Slows Stack
Multiple attack speed slows from different sources stack additively. If you're hit by Enchantress Untouchable (-150 IAS) AND Shiva's Guard (-40 IAS), you lose 190 total IAS. This can reduce you to the minimum cap of 20 IAS.
Attack Speed vs Damage: When to Prioritize Each
One of the most important itemization decisions for physical damage carries is balancing attack speed versus raw damage. Both contribute to DPS, but the optimal balance depends on your hero, current stats, and game situation.
The DPS Formula
DPS = Damage per Hit × Attacks per Second
To maximize DPS, you need to balance both factors. Stacking only one gives diminishing returns.
Understanding Diminishing Returns
Both attack speed and damage experience diminishing returns when stacked excessively:
Example 1: Adding Damage when Attack Speed is Low
Starting: 100 damage, 1.0 attacks/sec
DPS: 100 × 1.0 = 100 DPS
After +50 damage: 150 damage, 1.0 attacks/sec
DPS: 150 × 1.0 = 150 DPS
+50% DPS increase
Example 2: Adding Damage when Attack Speed is High
Starting: 100 damage, 3.0 attacks/sec
DPS: 100 × 3.0 = 300 DPS
After +50 damage: 150 damage, 3.0 attacks/sec
DPS: 150 × 3.0 = 450 DPS
+50% DPS increase
The SAME +50 damage gives the same 50% DPS increase, but the actual DPS gain is 3x higher when you have high attack speed (150 vs 50 DPS added). This shows attack speed MULTIPLIES damage effectiveness.
When to Prioritize Attack Speed
Prioritize Attack Speed When:
- High Base Damage: Heroes with naturally high damage (Sven, Tiny, Kunkka with Tidebringer) benefit more from attack speed
- Critical Strike: Heroes with built-in crits (PA, Juggernaut, Wraith King) multiply damage through crits - attack speed maximizes crit procs
- On-Hit Effects: Bash (Slardar, Void), Maelstrom procs, or Diffusal Blade mana burn scale with attack speed
- Low BAT: Anti-Mage (1.35 BAT), Juggernaut (1.4 BAT) get more value from attack speed items
- Damage Multipliers: Heroes with damage multipliers like Drow's Marksmanship, Sven's God's Strength, or Morphling's Attribute Shift
- Farming Efficiency: When you need to farm faster (jungle, lane creeps), attack speed clears camps quicker
- Building Damage: Towers and barracks take full damage from each attack - more attacks = more building damage
Best Attack Speed Heroes:
Phantom Assassin, Faceless Void, Juggernaut, Anti-Mage, Terrorblade, Troll Warlord, Sven, Monkey King
Prioritize Damage When:
- Already High Attack Speed: If you have 300+ IAS, adding more attack speed has diminishing returns - add damage instead
- Limited Attack Windows: Heroes who get limited attacks (Ember Spirit, Kunkka) benefit from maximizing damage per hit
- Burst Damage Needed: Against squishy targets or when you need to burst heroes quickly before they react
- Enemy Has Attack Speed Slows: Enchantress, Bane, Crystal Maiden counter attack speed - raw damage is more reliable
- High BAT Heroes: Doom (2.0 BAT), Treant (1.9 BAT) don't benefit as much from attack speed
- Armor Stacking Enemies: When enemies stack armor, high damage per hit with armor reduction is better than many weak attacks
- One-Shot Potential: Late-game scenarios where one-shotting enemy supports is important
Best Damage Heroes:
Kunkka, Ember Spirit, Sven (needs both), Morphling (AGI), Tiny, Clinkz, Bloodseeker
Optimal Balance: The Sweet Spot
For most carries, the optimal DPS comes from balancing attack speed and damage rather than stacking one exclusively:
Comparison: Balanced vs Stacked Builds
All Attack Speed, No Damage
Items: Moon Shard + Mjollnir + Assault Cuirass + Butterfly
Stats: 80 damage, 350 IAS, 2.65 attacks/sec
DPS: 80 × 2.65 = 212 DPS
Terrible: High attack speed but pathetic damage per hit
All Damage, No Attack Speed
Items: 3x Daedalus + 2x Rapier
Stats: 700 damage, 50 IAS, 0.88 attacks/sec
DPS: 700 × 0.88 = 616 DPS
Bad: Huge damage but attacks too slowly to use it
Balanced Build
Items: Butterfly + Daedalus + Manta + Satanic + Mjollnir + BKB
Stats: 350 damage, 180 IAS, 1.65 attacks/sec
DPS: 350 × 1.65 = 577 DPS
+ Critical strike multiplier (~2.4x) = ~1,385 effective DPS
Optimal: Balanced stats with utility and survivability
The balanced build has higher effective DPS and provides survivability (BKB, Satanic) and utility. Pure damage or pure attack speed builds lack versatility.
Item Priority Flowchart
Step 1: Check Current Stats
Look at your hero's current damage and attack speed
Step 2: Evaluate Ratio
Low Attack Speed (<150 IAS): Prioritize attack speed items
Medium Attack Speed (150-250 IAS): Balance attack speed and damage
High Attack Speed (>250 IAS): Prioritize damage items
Step 3: Consider Hero Kit
Does your hero have crits, bash, damage steroids, or on-hit effects? If yes, favor attack speed.
Step 4: Itemize
Choose items that address your current weakness while providing utility/survivability
Specific Hero Examples
Phantom Assassin
Why Attack Speed: Built-in critical strike (Coup de Grace) gives 450% crit damage. More attacks = more crits = exponentially higher DPS. Blur also gives evasion, so survivability is covered.
Best Items: Butterfly, Manta, Moon Shard, Assault Cuirass
Sven
Why Both: God's Strength multiplies base damage by 3x, making damage items incredibly efficient. However, still needs attack speed to apply that damage. Balance both.
Best Items: Daedalus, Assault Cuirass, Moon Shard, BKB
Kunkka
Why Damage: Tidebringer is a single cleave attack on cooldown. One massive damage attack with Tidebringer is better than many weak attacks. Damage per hit is king.
Best Items: Daedalus, Divine Rapier, Silver Edge, Armlet
Anti-Mage
Why Attack Speed: 1.35 BAT (exceptionally low) and Mana Break on-hit make attack speed extremely valuable. Each attack burns mana. More attacks = more mana burn.
Best Items: Manta, Butterfly, Moon Shard, Abyssal Blade
Drow Ranger
Why Both: Marksmanship gives +120 AGI when active (120 damage + 120 AS). Multishot scales with attack damage. Needs both for optimal DPS.
Best Items: Hurricane Pike, Butterfly, Daedalus, Silver Edge
Troll Warlord
Why Damage: Fervor gives +240 IAS at max stacks. Already has insane attack speed built-in. Needs damage to make use of it. Bash procs also benefit from high attack speed.
Best Items: Diffusal Blade, Satanic, Butterfly, BKB
