I love Devil Daggers and seeing a reference to it in the mod feels awesome. I can't seem to find anything for it, but do synergies for the item exist at all? I tried homing and that doesn't work, which made me sad but I guess makes sense.

Honestly I'd just take this as a game/tear modifier as a whole with the gem mechanic holding over per floor, it's a neat item that just feels a little underutilized, but maybe I'm missing something about it.
