Infected Liver

An infected organ from the Abyss

Infected Liver is a meat-type consumable that our records list for ARK: Survival Ascended; the ARK Wiki connects it to the Aquatica release. The game describes it as "An infected Liver. Can be used to apply infected augments to creatures."

Harvesting livers

The wiki points to the corpses of the Abyssal Therizinosaur and the Abyssal Thylacoleo, which live in the Abyss biome and which higher-tier Rifts also spawn. Corpses lying in the corrosive areas can give Infected Livers too, along with other infected parts. Stripping such corpses fully carries a risk, though: the wiki likens the spore debuff it gives to Aberration's fertile spores.

Barnacles and buffs

In the Infectarium, Infected Livers go into Infected Barnacles. Barnacles made with them raise the chance of putting a poison debuff on an attacker.

Both survivors and tames can eat it:

• Survivors: it deals 25 damage and restores 10 food. Movement speed goes up, and food and water drain rise by roughly 20%. The icon mentions extra melee damage, but the wiki says this appears to do nothing.
• Tames: force-feeding raises movement speed; it does not hurt the tame and does not boost its damage.

Eating infected body parts gives a 30-second buff. Another one eaten while that buff runs does not add to it; the countdown starts again at 30 seconds.

Weight and stacking

Each liver weighs 0.1, stacks to 100, and a full stack weighs 10.
