Fallen Down bypasses elemental affinities and ignores death prevention, useful for Mortal-heavy attacks and a sealed finish on minions. Its single-target opener lets you choose the priority enemy; the follow-up damages the rest and debuffs them.
Setup: Collaboration-exclusive; build MATK and max the active skill.
Watch out: Its damage reduction does not cover Almighty or Light.
Combat stats use the screenshot’s level, STR, MAG and VIT with the base stat formulas. Enemy skill bonuses are not included. HP is the recorded maximum.

Protect against Mortal and plan repeated minion deaths/revival. Karn Break prevents relying on repel to stop Yaxche+.
Activates the following Chain Effect when an ally is downed: Inflict Almighty (Magic) damage (Power: 200) on a random enemy, with 100% chance to inflict Mortal. Nullifies all death prevention skills. Won't activate when your party is wiped out.
Bring units that can Null Mortal and revive. P2 Nebiros works wonderfully. Purple Erlkonig will keep you healthy and should be able to tank anything this encounter has.
Repelling Yaxche+ is not an option since Ixtab has Karn Break.
You can repeatedly kill the minions until Ixtab runs out of Recarm uses, or simply seal them if you have a unit capable of doing so.
