This is a guide to what the base stats should be of quests that you accept based on your level, in order to maximize exp and stat gain.
The format used for base quest stats will be <base attack> <base strg> <base accy> <base hp>, and the format for weapon stats will be <damage>/<accuracy>.
When you hit level 20, the guide will give options for maximizing money gained from quests, and maximizing exp and stats gained from quests. Since most people maximize EXP and stats, the maximizing money route is less accurate.
