Poison

Poison is a new mechanic found in the Shipwrecked DLC. If a player Character is hit by a Mob or an environmental hazard that has a naturally poisonous attack they will become poisoned. When a character is poisoned, they will slowly lose health and sanity. The poison does not expire over time for player characters, they will stay poisoned indefinitely. The effects of poison can only be cured by consuming an Anti Venom.

The effect of poisoning will get progressively worse over time. Initially, poison will deal 2 damage every 10 seconds. For each day the character remains poisoned, the damage will be increased by an additional 10%. After 2 days, the period of damage application is reduced 10% for each additional day. As the damage increases, the poison effect in the UI will become more pronounced. The damage, frequency and the UI effects reach their maximum after 10 days, dealing 4 damage every 2 seconds. The sanity is lost at a rate of 6 per minute, and will not increase over time. While poisoned, player characters will gain a -0.2 hunger drain modifier, meaning characters with default hunger drain will get hungry 20% slower.

When fighting poisonous enemies, wearing a Seashell Suit or a Horned Helmet will prevent poisoning through physical contact, and wearing a Gas Mask will prevent poisoning through gas attacks. Stink Rays currently uses both attack types, therefore require wearing both a Seashell Suit or Horned Helmet and a Gas Mask to prevent poisoning from their attacks. WX-78 is immune to poison.

Poison can also affect Mobs, which reduces their damage and movement speed by 25%, and increases their attack period by 25%. Some Mobs are naturally immune to poison. It should be taken into account that upon a poisoned creature dying, all food items will instead be dropped at half freshness making them stale on drop. Poison lasts 120 seconds for Mobs, after which they will be automatically cured.

Trivia

 * Poisonous creatures except for the poisonous Spider Warrior cannot be poisoned.
 * Prior to Hang Ten update, food drops from poisoned mobs lost all their freshness instantly, making them Rot.
