Just a thought

While playing RotDS, I randomly started to think of the Tintina Bar. Would it be possible to alter its coding to where instead restoring HP with every step, it restores your MP. Because I never really had Problem of using Potions or magic to Heal, so I never really used that Relic. I just think it would be more useful if it restored MP instead. Though it would have the potential of breaking the game if you really want to walk that much for free MP restore.
