As in, a magic type that specializes in self-buffs and hand-to-hand fighting by focusing the users Mana to different parts of their body to enhance abilities associated with it? The main trade-off would be that users have a very hard time projecting their Mana outwards, with the limit effectively being a standard Magic Bullet.
As
@Remram said, Reinforcement Magic is sort of like the close-combat version of Magic Bullet--a generic form of magic that everyone can use regardless of element. But if you wanted to do something like this, maybe consider using some form of magic that's conducive to hitting hard or further reinforcing a weaponry or martial arts based style of fighting? Like, if you used Earth Magic to form stone gauntlets over your fists, or used Wind Magic to do some kind of like... "mini-tornadoes around the legs" for powerful flying kicks and such?
@RoadkilBanana I typically search something like safebooru or zerochan for anime-style face claims. I also don't
mind if AI generated images are used, it's just that most of the ones you can use for free don't always churn out the greatest results.
