Rising Force vs. Heavy Grav still has the Grav do 700 Damage, yeah. I'm seeing 799,300 right now.
Then hit him with an accidentally made Fire Formula III for 798,984 at the end of Brill's second turn, exploiting the expected Fire weakness in his defenses from my current loadout.
Oh, so it's damage dealt by the end of the battle, not damage done across the whole battle? Well, yeah, he needs to attack more and heal less then. mm.
Well, got 1153 damage with that calculation style and 258 ticks too, so I'm good, getting 288 points from that. Gonna go Hard Mode once more to get from 499 points total for the others needed for another Medal.
