Scarterran martial arts

So how does Scarterran martial arts differ from the martial arts in the real world and various fantasy worlds?   Just like in the real world, people have been trying to figure out more efficient ways to kill their enemies since the days of sharp sticks.   Scarterrans have the same reasons to fight each other that historical real world humans had. They also have to deal with a much wider array of different sapient mortal races and assorted magical beasts and other fantasy threats to deal with.   In the real world, there is a major limiting factor slowing down the societal learning curve of martial arts, and that it is hard to study new ways of killing and maiming people without actually killing and maiming people. One only get so far with advancement through sparring because no one wants to die or be crippled during training.   That is why in the real world we are not sure which martial arts style or styles are best for self-defense in life or death situations because no one wants to stab an opponent in the eye or groin in a sparring match.   Magical Healing is a game changer. While relatively rare, a master of Healing magic can guarantee any injury short of death can be completely fixed.   Even if the damage is reversible, most warriors are not willing to endure the pain of crippling injuries simply to advance the martial arts, but some are.   Most magical healers are not willing to use their holy arts to put people back together after brutal experiments, but some are.   Also, once a warrior perfects a technique for a gauging someone's eye or doing some other brutal combat maneuver, they don't have to keep doing it. They can teach the techniques to others without the need for magical reconstructive surgery.   Beyond this extreme example, Scarterrans rely on the common real world medieval training method of letting warriors wail on each other with blunt weapons. Given that it is relatively simple for a magical healer to heal these sorts of bumps and bruises (or even microfractures in bones) with even a little bit of magical healing warriors can train for longer periods of time and with less need for restraint.   The rudimentary power of the Wrath sphere can make any weapon temporarily non-lethal letting people train vigorous with their actual weapons rather than train with inelegant training weapons. The arcane spell, Merciful Weapon allows for this too, though the spell is relatively uncommon.   Theoretically, Golems and summoned spirits can help in training too.   All this together means that Scarterra, despite being a thousand or more years behind us in most science and technology, would have superior unarmed and melee martial arts to the real world just from brutal application of the scientific method.
