The Axe
Battle Potions and Calming Potions are fun and really useful depending on whether you need to fight some extra enemies or avoid them based on spawnrate. I know they already have the spawnrate functions, but I think the title would be a nice way to pair it up with the Aggro mechanic, Since it's only used in Hardmode and make logical sense (Enemies would be more primed to attack you if you wanted to battle after all, and vice versa for a calming experience). Is it too strong? I wouldn't really say so, a ±100 buff or so of Aggro wouldn't change that much for example, Just make it slightly more useful for each. What do you guys think?
