I just started playing this game.
Started by getting Mokou. I wasn't willing to waste an hour to get Byakuren.
Beat up Mei- I mean China :3
Then got through Stage 1 no problems.
Stage 2 was also easy, but took quite a while. Against the bosses, Aya's Sleep Beak procced 2nd turn on Nitori. Although I used the wrong immunity to counter Red Magic, Reimu, Sanae and Mokou got Charmed... Mokou instantly snapping out before getting whacked by Goheis.
Still, took Remi down, and Nitori was rudely awakened from her snooze and quickly beaten.
Then proceeded into Stage 3, where I proceeded to get lost. Still, my new party, Aya/Sanae/Mokou/Sakuya/Patchy is very effective, especially with Nitori as a commander. We basically started to curbstomp everything in the forest after Patch got more than 4HP, and Aya got Tengu Support, includeing Alice. It's wonderful wiping out large mobs instantly due to an Aya/Patch combo boosed with Nitori's commander bonus to elemental damage. Not sure why I've heard most people don't use Aya.
Sakuya's single target damage is insane.
Started Stage 4, where I've hit over 900's with Sakuya when Claymore's Slayer is applicable. Those poor Hell Serpents.
I get the feeling I should make room for Alice, probobly in Mokou's slot. But right now PATCHY NUKE is killing pretty much everything. Especially since most the mobs in stage 4 seem weak to Water.
