What Unstable Does

Unstable makes the Pal's SAN drop 10% faster — the milder version of Destructive (+15%) and the exact mirror of Positive Thinker (-10%). Sanity mostly drains at base while Pals work, so this is a worker problem: more breakdowns, more hot-spring breaks, less time at the station. On a Pal used purely for combat or riding it barely registers.

How to Get Rid of It

Overwrite it at the Pal Surgery Table with any unlocked passive — even the 10,000-gold default Positive Thinker flips the slot from +10% SAN drain to -10%. Unstable isn't on the surgery menu, so once overwritten it can't be re-applied; the implants guide covers everything that can take its place. When breeding worker lines, cull carriers or fix the finished Pal with one cheap surgery.
