Larva

Larva is a Creature in Abiotic Factor (codename A299 A), originating from The Hive. It has 50 head HP. Its melee attack hits for 35 Sharp damage.

It is weak to Fire damage — the hardest-hitting of the 5 weapons here that deal it are Magma Skink (Weapon) (180 dmg), Thresher (60 dmg), and Grinder (45 dmg). Bring the matching damage type and it dies fast.

It resists Acid damage, so avoid leaning on those types even if your best weapon uses one.

Harvestable from it: Raw Larva Meat, Larva Figurine. Bring the tools to collect these or you lose the drop.

Verdict: Overall Larva is a Creature — kill it with Fire damage.
