I'm semi-interested. I dont really have qualms with the not all-inclusive sheet, because I rarely use comprehensive sheets myself, but what a character can do, and what scope it can be done should always be known on at least some level.
That said, the only real insurmountable issue with the sheet I see is the damage percentages listed on your equipment. Given this place doesn't seem to run on numerical stats at all(mana, hp, dexterity, etc.) those numbers might as well be 1 or 3,000,000 because no one would know how to translate those percentages in a reliable way to the fight. Now I'm familiar with ff7, and the concept of material, but what exactly does 'negate death' mean?
On that topic, I noticed some other things, like 'light null' and 'dark null'. So he's just straight up immune to light and darkness?
