They should go directly into your inventory And 'sporing' corpses should be made less tedious, (aka activated ability to spore corpses in range, or the like)
For that reason alone, I'd rather spores go into the hand. That way I can use the ability and drop it on a corpse immediately after. Lockpicks can go right into the Lutefisk Cube. Do not implement this. Edit: Or make it optional.
