Calculate your total attack speed with Kraken Slayer and other items. Compare build paths and optimize your ADC itemization for maximum damage output.

Attack speed in League of Legends is multiplicative. Your base attack speed is multiplied by your total attack speed percentage bonus. For example, if you have 0.625 base attack speed and 100% bonus attack speed from items and runes, your total attack speed is 0.625 × 2.0 = 1.25 attacks per second.
Kraken Slayer provides +25% attack speed and is considered a Mythic item. It applies on-hit effects and deals bonus damage on every third attack to the same target. This makes it one of the most cost-efficient attack speed items in the game and a core purchase on most ADCs.
Items like Berserker's Greaves (+45%) and Nashor's Tooth (+25%) provide significant attack speed. When stacking multiple items, their bonuses multiply rather than add linearly. Always consider your champion's itemization path, win conditions, and whether you're building for sustained damage or on-hit effects.
League of Legends has a hard cap at 2.5 attacks per second. While technically you can build more attack speed, hitting this cap means you won't attack faster. Plan your builds to reach optimal damage without overbuilding unnecessary attack speed that provides no benefit. Some ADCs can reach this cap, while others benefit more from other stats.
Kraken Slayer is almost always your first or second item on ADCs. It provides excellent value with attack speed and on-hit damage.
Build paths differ: crit builds (Infinity Edge, Essence Reaver) or on-hit builds (Guinsoo's, Nashor's, Runaan's). Choose based on your champion.
Always include defensive items like Maw, Force of Nature, or Mercurial Scimitar. You can't deal damage if you're dead.
Don't follow a rigid build path. Adapt items based on enemy composition and what's threatening you in fights.
While attack speed is important, remember that crit, damage, and defensive stats also matter for effective DPS.
Most ADCs benefit from Kraken Slayer, especially those with auto-attack focused playstyles like Jinx, Ashe, Miss Fortune, and Kai'Sa. The on-hit damage and attack speed make it efficient on champions that attack frequently.
Not always. If the enemy team has significant crowd control or magic damage, Mercury's Treads or other defensive boots may be better. However, for pure damage and attack speed, Berserker's Greaves is optimal.
Most ADCs can reach the cap with a full build. However, some champions like Aphelios start with higher base attack speed and can reach it with fewer items. It depends on your champion and your itemization choices.
No. While attack speed is important, other stats like crit damage, armor penetration, and defensive items also matter. Balance your build based on your champion, enemy composition, and game state. A well-rounded build often outperforms one that overinvests in a single stat.
Crit builds focus on critical strike chance and damage for burst damage. On-hit builds stack attack speed with items that trigger on-hit effects (Kraken Slayer, Nashor's Tooth, Guinsoo's Rageblade) for consistent, high damage output. Choose based on your champion and playstyle.
Use this calculator to compare different itemization paths and see which provides the best attack speed for your champion. However, remember that numbers don't account for gameplay dynamics. Test builds in-game, particularly in ranked or custom games, to see how they perform in actual combat.
Attack speed runes are valuable for early game laning and scaling into late game. They provide solid damage increase without significant trade-offs. Consider the trade-offs with other rune options, but attack speed runes are generally recommended for most ADCs.
Understanding attack speed is crucial for ADC success. Use this calculator to experiment with different item combinations and find the optimal build path for your champion. Remember: theory meets practice in real games, so always validate your builds through gameplay before committing to them in ranked.
