id say balance refines until they are lvl 7, cave keys, bells (get at least lvl 30 across pos.1), and myoboku (dont prioritize after lvl 8 for all maps). Remember to always use rebates when spending those things (refine rebate, and cave key rebate). refines are lvl 7, and myoboku is lvl 8, u want to use nearly everything on cave keys. U need at least 1050 of them every rebate (once a month give or take a week), to get ultimate essence. If u are going to be competitive, go for 2100 cave keys every rebate, using moon only on cave keys, and using cpns to fill the gap to get 2100 every rebate.
