For Demons, i ended up using the meat cleaver, a sh*tload of strength, and of course a Damage Buff up always. the Damage was insane... even on NG++++++, i had no Probs with it.
@else: Started playing Phantasy Star Zero, level 59 right now... the only thing that keeps me from 'Super' difficulty, is the 'Eternal Tower'.. gosh, why did they implement a Quest you have to work on for like 8+ Hours without the possibility of turning your system off inbetween, lol. XD
