Where It Drops
| Stage | From | Box | Weapon | Per kill |
|---|---|---|---|---|
| 2-9 | Normal monsters | 1.77% | 40.8% | 0.72% |
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 Chopper is in the squad (one weapon box in three with a full squad of three). Before Engraving bonuses to drop rates.
Also listed for 2-10 (normal monsters), where the box chance is 0%: never dropped there.
Chances from StageDropConfig, read the way the game's code (DropController) rolls them.
