Per kill: the chance of a weapon box; it is one of the weapon boxes of the heroes in your squad, picked at random, so this one only drops while Mori & Gula is in the squad (one weapon box in three with a full squad of three). Before Engraving bonuses to drop rates.
Chances from StageDropConfig, read the way the game's code (DropController) rolls them.
