When challenging an Elite, the ideal route is one that leads to a Rest Area immediately after. If you are low on HP or Stress, don't push yourself, and consider a strategy that avoids Combat Areas and Elite Combat Areas.
Strengthen Cards Through Combat in the Early Stages

Immediately after entering Chaos, you only have your Starting Cards, so you cannot perform powerful actions. Repeatedly engage in combat during the relatively easier early stages and aim for an Epiphany.
Acquire Equipment Before the Boss Battle

Combatants are strengthened by acquiring equipment. This also contributes to the strength of the created Save Data, so aim to acquire equipment before the boss battle.
Guaranteed Acquisition from Elite Battles
In battles with Elites that occur in the purple areas, you are guaranteed to obtain equipment upon victory. Powerful enemies await, but if you have the strength, you should try to fight them.
Prioritize AoE Attacks
It is important to defeat the minions for both bosses in the Blue Pot. When building your party or acquiring common Cards, prioritizing AoE Attacks will make the boss battles easier.
Elite Enemy List
List of Elites and their Features
Enemy | Features |
---|---|
![]() | Gains Fury whenever a Combatant uses a non-Attack Card |
![]() | Draws Cards on Attack + Attacks again if it's a debuff Card |
![]() | Increases the Cost of a random Card at the start of the turn |
![]() | Damage increases based on the number of locked Cards |
The monsters listed above appear in Elite areas. Using too many Cards can sometimes strengthen the enemy, so make sure to have a solid grasp of your opponent's features.
