Poison

Poison is a debuff which deals damage over time based on the number of stacks applied, scaling exponentially in intensity with its stack count. When a poison tick occurs, the afflicted is dealt poison damage equal to the number of poison stacks, and then one poison stack is removed. Poison debuffs tick every 10 to 2 seconds for players (longer ticks achieved with higher poison stacks), or a fixed every two seconds for dungeon monsters and bosses.

When poison is first applied to an unpoisoned player, a minimum of 3 stacks are initially applied even if the poison source is trying to apply fewer than 3.

Poison stacks cannot exceed 10% of the afflicted's max health. Poison stacks also cannot exceed a hard limit of 750 stacks. When poison attempts to be applied beyond the maximum stack limit, the excess stacks are converted into immediate poison damage equal to the excess stacks.

Poison damage ignores armor and most other damage modifiers.
