((Speaking of which, mana rules.))
Basically, this system will take over from Emp's multiplier system. Every character is subject to mana use.
Mana is calculated by the following equation
50 (everything has 50 base mana, even Muggles)+ MAG(if magical)/MIND( if Persona/superpower)x5
Mana is only used in alternate forms if applicable.
Mana usage will be divided into several categories.
Manaless: These acts lack any mana costs. They are either mundane or very weak (conjuring a small illusion, moving a rock with your hand, etc) or have another, very serious disadvantage (Anima's ults are Manaless precisely because she loses a summon per ult, Ashley is unable to move after using hers, Ciro doesn't use mana in Laeveteinn because she ends up in a coma afterwards).
Minor: Small acts (blasts of wind, first tier Persona spells, basically anything that only hits small groups or single people). These will cost 5-10 mana.
Moderate:Moderate acts (short-range teleportation, hitting a large group with fire, middle tier Persona spells, etc). These cost 10-20 mana depending on the act.
MajorStrong acts, costing 20-30 mana.
Mighty Very powerful acts. 50+ mana.
For the purposes of mana, Summons use their summoner's mana, but summoning in itself costs no mana.
