my power system involves three types of magic.
projection manipulation, the ability to send out mana, improving this manipulation allows you to increase the range and control of the mana you send outwards.
enhancement manipulation, the ability to condense magic down to make it stronger and more powerful. Using enhancement on the body protects the user from drowning andd other environmental factors but also strengthens the body. improvining it will increase how much you can condense your mana, giving you stronger attacks overall.
support manipulation, the ability to manipulate the mana in your own and other peoples boddies. Improving it allows you to control the mana within your and the other persons body with more ease. Attacks using support mana can affect internal organs of the opponent, however moving and controling your mana in someone who is well versed in enhancement manipulation is increadibly hard unless your stronger than them.
