Скачать или смотреть Another Eden - Unseen 2 Turn Kill with Melissa

Yeah, Melissa makes this very, very easy.

Turn 1 AF to build stacks and bring to 25% HP stopper, and then just slam it.
She also does decent damage herself.
I think Yuri's two move combo (as with other similar attacks) have chance to inflict pain on both, but I haven't yet had a case where first hit doesn't inflict pain and second does, while I have had one case where first and second both failed, so who knows. Second hit does inflict pain (as AoE on other targets) but yeah.
I could also skip Lunatic on her and instead apply Break for Thillelille's Eclipse Blade, but eh. I messed up my clicking here (Coil from Cress is totally unnecessary) but oh well. Enough is enough.

Better farm the boss to trade for the goodies, including Almighty Power (Western) and Chant Script.

...and compared to that, Power of Crystal is sucky at +20% -_-;
It's T3 Grasta but yeah. Dormant Ore makes it +30%, just like T2 elemental. It's... not exactly great. I was thinking about giving it to Melissa but I don't think it's really worth a slot if there's a pain unit.
