Poison is a Damage Over Time combat debuff that comes in two flavours:

  • Poison, which deals 10% of the target's maximum HP over 10 seconds.
  • Deadly Poison, which deals 25% of the target's maximum HP over 10 seconds.

Despite the name, deadly poison isn't an effect that has a realistic chance of killing the player, provided they have sufficient Food and have purchased Auto Eat.
