To increase the viability and usage of Reaper poison I suggest that you allow it to be placed on the hotbar, and when you use it, it applies to your currently wielded weapon. If your weapons are sheathed it will do nothing, and to avoid poison spam put it on a cooldown just barely long enough to allow poison stacking if you’re on top of your game but the average person would have trouble maintaining.
I think poison should be applicable to all weapons, not just daggers. Poison is a time honored tradition with weapons. Bad enough that Bleed can mow through a raised shield every time like it’s not there.
