Brands do not, ordinarily, level up. I also have thought about an upgrade that allows you to “refresh” one to your current level; undecided if I’ll do it or not or any details about cost/cooldown/etc. though. Somewhat similar to why demons eventually slow down in leveling as they get far from their starting level, I’m not sure I want one awesome Brand find on Tower:2 to be all you need to carry you through the entire game.

PerfectHealth requires your HP to be equal to your MaxHP: it doesn’t care what your MaxHP is or if it has been modified or not. It will probably be a decent sized bonus. Maybe not outlandishly crazy high though: while HP = MaxHP is difficult for melee characters and a bit tricky for projectile users who need a line of fire (and thus always offer one to enemies), it can be somewhat easier to keep for healers/status appliers who don’t need to get very close or have a line of fire. It also can potentially be easy to keep for any character using life-drain attacks or with high enough defenses to discourarge AI attacks… though the AI will probably be aware of PerfectHealth brands and may act accordingly.

Granted, any nonsense like Mind Scream and the like will always knock you out of it no matter what… but if it wasn’t a problem sometimes it wouldn’t be worth giving a bonus for.
