All battles last 2 rounds by default. Every 10 chapters, turn all panels into Player Encounter panels. Those fights will last 10 rounds. Gain +1 of a stat of your choice every Norma Level Up.
(Achievements are disabled with this mutator.)
Rule Changes
- Every battle lasts 2 rounds by default.
- Upon achieving a norma objective, a window will appear displaying the player's base stats. The player must select either ATK, DEF, or EVD to increase that base stat by +1 (up to a max of +3). These boosts are represented through the Chaos Muscle, Chaos Guard, and Chaos Speed stock effects.
- Every 10 chapters, the Chaos Battlefield field event will occur. Lasting for one chapter, this replaces all panels on the board (including
Home and 
Warp panels) with 
Player Encounter panels and disables the option to stop on home markers. - Triggering a Player Encounter panel will start a battle against another random active player on the board. The player who triggered the panel attacks first. Any battles initiated this way last 10 rounds by default.
- Every character has their base REC stat divided by 2 (rounded up).
Notes
- Chaos Battlefield is a unique field event exclusive to this mutator.
- Player Encounter panels are a unique type of panel exclusive to this mutator.
- If a character's base stat is already at +3, that stat will be greyed out upon level up, and cannot be selected to receive a boost. Only a character's initial base stats and existing Chaos boosts affect this (all other stat buffs are ignored). If a character manages to receive a Chaos boost for a stat which would take them above +3, the Chaos boost will not apply.
- , , , , and have passives that cause their base stats to fluctuate, meaning they are able to get Chaos boosts in one form that they would be blocked from acquiring in their other form. This means certain boosts may only be applied in one form while being wasted in the other form.
Poppoformation changes all base stats to -1/-1/-1, allowing any character to acquire a Chaos boost that would normally be locked for them.
Cast Off causes all base ATK to be seen as base DEF, and vice versa. This means that during Cast Off, having a lot of base DEF will instead block you from selecting ATK boosts, and vice versa. This can be used to potentially gain useless extra boosts in either ATK or DEF.
- Player Encounter panels do not count as
Encounter panels for the purposes of any effects that interact with Encounter panels. 
Crystal Barrier can cancel a battle initiated by a Player Encounter panel, but only if the player with Crystal Barrier is not the one who triggered the panel.
