Elite Training Floor 1 in one attempt

I tried to make this run as fast as I could while minimize the RNG. There are just three turns when the run can go wrong:
19 turns left: Richard should inflict Sword Resistance down
16 turns left: Richard should inflict Sword Resistance down
11 turns left: H'annit might die this turn, it has happened to me 1 in 10 times

I was super lucky with my pulls in the 2nd anniversary and got the stone for H'annit's EX Ultimate. The Signa/H'aanit EX combo is great and I think it is necessary to have the Ultimate Debuffs for most of the fight to pull this run.

I'm using several A4 accessories, but with free accessories this should also work with more turns for preparation.
