Quill Rifle

Quill Rifle is a Science Ranged in Abiotic Factor. It deals 35 damage of the Sharp/Acid type. It is a Tier 5 item. It weighs 8 per unit. In-game it is described as: "A re-engineered bioweapon, turning Exor quills into deadly homing bolts that stick into targets and coat them with acidic residue."

A science-tier ranged weapon — it draws on the facility's own tech and typically trades conventional ammo for energy or exotic payloads.

Its 35 damage places it mid-pack of the 22 Science Ranged entries tracked here (#11 by raw damage).

Against the enemies catalogued here, 19 are weak to Sharp/Acid damage — including Armored Exor, Jotun, Jotun of the Fallow, and 16 more — so this is worth carrying before those fights.

Practical notes: it has 45 durability before repair.

Verdict: Overall Quill Rifle is "a middle-of-the-pack Science Ranged" pick whose Sharp/Acid damage profile should be matched to enemy weaknesses.
