What Idiosyncratic Does

Idiosyncratic is a one-slot survivability package with four effects:

• Defense +25% — nearly Diamond Body numbers.
• HP Regeneration +50% — for both the Pal and you, its trainer.
• Burn immunity and poison immunity — the two damage-over-time ailments, gone.

No other passive covers stats, sustain, and status effects at once. It's the pick for tanky all-rounders and for fights built around burn or poison pressure; pure stat tanks may still prefer Diamond Body for the flinch and knockback immunity, and pure damage sustain belongs to Immortality .

How to Get It

Idiosyncratic is one of the five mutation passives — it never rolls on wild Pals. There are two sources:

• Mutated Eggs. Every Pal hatched from a mutated egg carries one of the five mutation passives at random — see the mutated Pals guide. Community testing shows the passive then inherits through normal breeding like any other.
• The disposable implant. Disposable Implant: Idiosyncratic applies it at the Pal Surgery Table (free surgery, implant consumed). It only drops from recycling Glistening Ancient Relics at the Ancient Relic Recycler — a 20% roll in the Glistening-exclusive slot. See the Ancient Relics guide.
