Erasing Mirror Dungeon with Burn, Bleed, and Poise.

The main focus for this loadout is Ryōshū's Bad End ID and The House of Spiders.
Her goal through the fight is to kill off each House of Spider ID and obtain their unique buffs while activating Team E.G.O. Gift conditionals. Having the "Spiderweb Entangled in Red" E.G.O. gift enhances this team.
The Deployment order for The House of Spider IDs are very important as they dictate which IDs die first. Blade of the House of Spiders Ryōshū's Evade skill targets the ID with the earliest deployment.
The current deployment order is recommended for survival in early turns. As Ryōshū kills the House of Spiders, the conditions for each E.G.O. gift gets fulfilled, starting with both burn and bleed, and then poise.
You can use Yi Sang's Fell Bullet, Outis' Magic Bullet, and/or other E.G.O. corrosions to help trim down the team.
And when all is done, only Ryōshū will remain.

Happy Fusing. Happy Erasing. Happy Burn Season.
