Zoe route only (serum to Zoe): Wrecked Ship S2, No. 2 Engine Room, on the floor in the SE corner. Ethan arrives with an empty inventory and it is his only weapon against Mia.
Verdict
Scripted weapon for the Mia fight (700 HP); it disappears afterwards.
Handle it like the Axe: guard and swing when Mia staggers.
