The best stat is for sure the WIT for more IP Speed and Action. BUT in fact all stats are important. STR for make more damage and HP/DEF if you don't want to be "OneShot By Baal ©" Probably the less important is Agl (but you need it too, just a few).

Anyway, Feena is more & more weaker during the Disc 2, Rapp have a powerfull SP Attack without ACT Charge, Liete have a lot of manapoint + A 100% Cancel SP Attack. Feena is just here for heal partners.

because if a moderator has already said yes without a run video proof, why that person have the right to be on the leaderboard and another not ?

Seems totaly unfair, rules is rules, for everyone.

For books I used, It's for Chaos mode, I don't know why I used same books on my Normal Mode run !
