Iai Strike Build

I'm really working on getting my Iai Strike I really need it for beating Feral Chaos.
I got my my multiplier to 99.9 but i'm not doing the "Iai Striking". I got equiped

HP=100%
Armorless
Near Loss
Large Gap in HP
Large Gap in Brave
Attacking Bravery
Hatless
Level 1-9
Level Gap >= 90

I know their are things like Smithing Soul, Side by Side, and Safety bit but I thought they were optional. Tell me if I'm doing anything wrong or need something else to help thanks in advance!

>>> Dont you need luck for Iai strike? (well, Im not really sure since I dont use it).. :luca:

BTW, if you are having trouble with Feral Chaos switch the difficulty level to "Moderate", that way he will be a lot easier..
