I know I have several posts that I probably could have just edited this into but, honestly, this is an OP enough exploit that I wanted to make sure was known. When switching morphs, you can change to a low health mob, like a tiny slime, who's max health is .5 heart. Of course, the mod still considers this to be full health and you can be below .5 heart without dieing so switching to the tiny slime will always put you at full health. Then you can simply switch back to the player and instantly be back to full health. Essentially, this gives the player a way to regen all their hearts in less than 5 seconds. Add on top of that that you can spam right click with either a blood orb or dagger of self sacrifice while morphing from a low health mob to a high health mob which can give you boat loads of blood totally for free. You could easily get 1,000,000 LP in under 30 minutes. That's how bad we're talking here.
