Went for that hardcore swaf, here's what I got. Not quite a ToD, but that's fine since this is some of the most impractical shit ever, like any good lab combo. I'm done maximizing her damage, for the most part. Numerically speaking, the combo does 408 damage and RD's maximum health is 420.

Even though there's a cooldown timer on D missile gem now, I found a way around it by basically stretching out the walk frames and triple jabs as much as I could so that the timer finished basically the frame or two before I summon the gem.
