I was randomly doing bosses and had to fix my morehearts chestplate, and i put it on and went back to my sword. But i noticed that when i went onto my sword, i gained an extra heart. I tried something out and realized that if you apply your morehearts chestplate and rapidly switch between two tools that have regeneration on them, your hearts skyrocket. Through further research, i found out that you can do this while in /pvp or in /fight and you will literally never die, because you can switch between the two weapons really fast and keep your hearts up. Please fix this bug.
