What is MP~ ?

One of the stats available to you is MP~ (that's just the default name, you can rename it) The purpose of this stat is not obvious, so permit me to explain. What it does is reduces, by a percent, the amount of magic (MP) that the hero or enemy needs to spend to cast a spell. Some possible uses include; Making a special item which gives you a stat bonus of 50 for MP~, thus letting the hero who equips it cast all spells at half price, like the "Golden Hairpin" item in Final Fantasy 6. Or, give an enemy 100 MP~ so that it can cast the same spells that other enemies cast without ever running out of (or even using) MP
