How Lethal Tempo works
Precision · KeystoneLethal Tempo grants 6% attack speed (4% ranged) per champion attack for 6s, up to 6 stacks; at max stacks attacks deal 9–30 bonus adaptive damage (6–24 ranged).
- The on-attack damage grows by 1% for every 1% bonus attack speed you have, so it scales strongly with attack speed items.
- Stacks refresh for 6 seconds on each attack, so it needs sustained fights against champions to reach full value.
- Fits auto-attack carries who build attack speed and fight for long stretches; weaker in short burst trades.
