ANOTHER GODAMN UI PO-oh wait it’s actually relevant this time.
Jokes appart, good idea. But I’d rather say being left at 5% life for MUI rather than one HP, cause that means that if you were in mid air, you’ll probably die from the fall, which would be ridiculous for someone who masters a above-god level power. And also, it simply wouldn’t be fun to die each time you do an air fight or are more than two block above the ground.
5% is low enough to be in great danger against almost any opponent.
