Yi Sang

The House of Spiders: The Index Nursefather

“A life wherein one is granted not choices to make, but instead, choices made… *beep* Hah. Would that my darling daughter, too, could have felt the mirth that colors such a life.”

Review

Mirror Dungeon tier

Poise and Sinking nuke with Furioso

The strongest Yi Sang by a mile. He follows Index prescripts to unlock stages that turn his coins Unbreakable, then fires the nine coin Furioso-Replica every three or four turns. His damage and survivability are very high, and he can cancel his first stagger.

Worth pulling?: must pull
Uptie: Not covered. A new boss identity, so he works well as released.

How to play

Open with the evade to reach Unlock II. Use marked skills against the prescript target to build Procuration -Hermes-, then fire Furioso at 9 stacks. After Furioso he stays in the strongest state.
