I just found out the crafting recipe for various debuff potions and while that seems like it would be useful to have, I fail to see its use. This is because, while I have plenty of the potions, I can't seem to actually deliver the effects to the enemy. My only option for these potions (that I can see) is to chug them myself, which is far from ideal.
Is there some way to apply the effect to the enemy or is there a possible reason I would want to drink these myself?
