i recently bought some nightmares from magincia for between 5 and 12m, but the elemental resists were all 35ish. i dont know the ratings. i didnt realize theres not a huge difference in hp or stats in nightmares, and as im using this (not just buying for rating / collecting ) since the resists are already low 5 resists isnt a huge deal to me.
So i dont know if that helps.
