A Simple Explanation of Magic!
(Have I used enough exclamation points yet?)

Magic is written in simple Algebraic expressions such as

"(+HP)=MAt/2R"

This may seem complicated at first, but just let me break it down for you.

On the left side of the "=" is whether a spell or attack adds or subtracts HP, MP, or status.

On the right side of the "=" tells how much or how easily this is done using your stats.

An extra letter signifies the element to which the spell is attributed

A direct translation of (+HP)=MAt/2R is "Hit Points added to the target's total Hit Points  is equal to one half the of caster's Magic Attack Rating using the power of Restoration"

Example:
(+20HP)=40/2R on living
(-20HP)=40/2R on undead

Added elemanets can be:
Earth, Fire, Water, Air, Lightning, Ice, Venom, Order, Chaos, Holy, Evil, Time, Space, and Restoration (Signified by its capital).
