Final Fantasy 7 Ever Crisis Ifrit and Bahamut EX2

Unfortunately my sephiroth is way too strong. I tried nerfing him by removing my Ice arcanum costume. This still works with an ob0 Kuja blade.
concentrate on bringing bahamuts health down as low as possible before killing ifrit.
Stat Requirements:
Myhtril Rod OB6 or Syringe Rapier.
Heal 2200. 2100 is probably enough as well.
10k hp, 170 mdef, 125 pdef
or 9k hp, 200 mdef, 150 pdef
mdef can be lower by adding fire resist but I choosen to boost mdef so it makes surviving bahamut's mega flare a ton easier if you happen to lack atb or mess up setups.
If you find that you can't charge shiva up fast enough to use her a second time before ifrit dive attack you can save her instead of using her instantly during sigil break.
