Infected Blubber

An infected part from the abyss

A meat-type item, Infected Blubber is tied by the wiki to the Aquatica release; our records list it for ARK: Survival Ascended. The game describes it as "An infected mass of blubber. Can be used to apply infected augments to creatures." The wiki gives it two uses: as a component for Infected Barnacles, which are made in the Infectarium, and as something survivors and tames can eat.

Harvesting Infected Blubber

The source the wiki names is the Abyssal Moschops: kill one and harvest the corpse. These creatures live in the Abyss biome, and lower-tier Rifts spawn them as well. A second source is any corpse in a corrosive area, which can be harvested for several kinds of infected part, blubber included. Stripping such a corpse completely leaves the survivor with a spore debuff, which the wiki likens to Aberration's fertile spores.

Barnacles and electric resistance

In the Infectarium, the blubber goes into Infected Barnacles. According to the wiki it raises the chance to shrug off stuns from the Electrophorus, Chrysaoras and Cnidarias.

Eating it

A survivor who eats a piece takes 25 damage and regains 10 food. After that, movement speed goes up while food and water drain about 20% faster. The buff icon also mentions melee damage, yet the wiki found no effect on it. Force-fed to a tame, the blubber raises the creature's movement speed and does it no harm. The buff runs for 30 seconds; eating another piece while it is active does not add a second buff but restarts the 30-second timer.

Weight and stacks

Each piece weighs 0.1 and they stack to 100, so a full stack weighs 10. The wiki files it under meat and gives it a spoil timer, so it does not keep forever.
