Castoroides
Castoroides Overview
In ARK: Survival Ascended, Castoroides occupies the harvester niche - earns its keep through resource gathering, making tedious farming runs much faster. As a herbivore, it responds to knockout taming - favoring Superior Kibble - and ships with 100% base Melee Damage, giving it solid damage output. Reproduction is by live birth following gestation; juveniles mature over a lengthy period. Its harvest profile centers on Hide, Raw Meat, Pelt, making farming runs noticeably faster. It earns its place in the stable for survivors looking to graduate from early-game tames.
