The Poison (毒, Doku) is a type of problematic debuff most notably to gradually damages the unit's HP time by time.
The effect may inflicted to any party.
Poison is not to be confused with Miasma. Poison damages the unit's HP time by time(approximately between 3.5 seconds until 4 seconds) and reduces HP based on the unit's maximum HP(12% max HP).
Poison is the opposite of Regen . It's possible to have both statuses at the same time, HP recovery or debility is ignored however.
