Pathfinder Remaster. Stats use the Pathfinder Remaster rules from Pathfinder Monster Core 2.
The Vaspercham is a Level 17 creature, with Armor Class 41 and 335 hit points. The vaspercham is a titanic, deep-sea aberration that radiates a field of chaotic energy, twisting the spells of nearby casters into unpredictable forms.
Saving Throws: +1 status to all saves vs. magic Constant Spells. A constant spell affects the monster without the monster needing to cast it, and its duration is unlimited. If a constant spell gets counteracted, the monster can reactivate it by spending the normal spellcasting actions the spell requires. +1 Status to All Saves vs. Magic Magic-Warping Aura (arcane, aura). 30 feet. A vaspercham's shell distorts nearby magic. Any creature in the aura who Casts a Spell must attempt a DC 37 Will save. Critical Success The spell is unaffected, and the caster is temporarily immune to the magic-warping aura for 1 minute. Success The spell is unaffected, but if the spell allows a saving throw, the vaspercham gains a +1 circumstance bonus to save against it. Failure If the spell has a target and there are one or more viable targets within its range, the spell's target changes, determined randomly by the GM. If there's no other possible target within range or the spell has no target, the spell is disrupted. Critical Failure The caster instead Casts another Spell, choosing randomly from their spell repertoire, prepared spells, or available focus spells (as appropriate) and selecting any targets at random. Hallucinatory Brine (arcane, illusion, mental). A creature hit by the vaspercham's Strikes or Mindwarping Tide must attempt a DC 38 Fortitude save. On a failure, the creature is overwhelmed with phantasmal visions, becoming Confused for 1 round (1 minute on a critical failure). Mindwarping Tide (1 action) (concentrate). The vaspercham releases an effusion of noxious water from its shell. Creatures within a 15-foot emanation must save against the vaspercham's hallucinatory brine. Whipping Tentacles (2 actions). The vaspercham makes four tentacle Strikes, each against a different target. These attacks count toward the vaspercham's multiple attack penalty, but the multiple attack penalty doesn't increase until after the vaspercham makes all of their attacks.
