Twitch Ability (LoL): Deadly Venom

Twitch's basic attacks poison his target with Deadly Venom, each attack adding one stack and refreshing its duration on-hit.

Each Deadly Venom stack deals 1 / 2 / 3 / 4 / 5 (+3% ability power) true damage every second over 6 seconds (depending on level), stacking up to 6 times for a maximum of 6/12/18/24/30 (+18% of ability power) true damage with each tick (depending on level).
