okay, i annhilated the emerald weapon (underwater) but the ruby weapon (desert) is too tricky for me i guess. i know the routine: W-Summon, Knights of the Round, Mime, and Final Attack linked with Pheonix but I need extra help. can anyone help me?
Ruby is weak against Hades/ Stop.
Try putting HP absorb on to KOTR.
Start the fight with only one character alive and use phoenix after it digs its claws under the ground (use Big Guard to survive with one character until then).
