tips on defeating Penace the hard way

[Adramelech_scott]

have any of you got any tips on defeating Penace the hard way and that means not using Yojimbo's Zanmato because i always do that

[sdruk12]

you should go train at hthe monster arena or the omega ruins i found monster arena was better but you know any1 will do that is the way i defeated penance i had 56,890hp somewhere round that number with all my characters i had max strength and defence and all the others were pretty high but you got to take his arms out first and use aeons (except yojimbo)
so to sum up:
1. train
2. take out arms (note: his arms grow back)
3. summon aeons (except yojimbo)
4. keep repeating process and you should beat him (it worked for me)
