Ghosthands is currently applying to owner's "on-attack" effects, preventing their usage. The two weapons I've noticed this affecting are both Bakaga Shuriken (Smoke tile spawn), and Seed Sniper (Vine Spawn on following turn). The moment you unequip your ghosthands, both these effects work again, which means Ghosthands is applying to yourself for some odd reason.

I should clarify this is only affecting on-attack effects rather than on-hit. On-hits are currently working as intended with the item.
