Formian Mageslayer

Tremorsense allows a monster to feel the vibrations through a solid surface caused by movement. It is an imprecise sense with a limited range (listed in the ability). Tremorsense functions only if the monster is on the same surface as the subject, and only if the subject is moving along (or burrowing through) the surface.

A monster with telepathy can communicate mentally with any creatures within the listed radius, as long as they share a language. This doesn't give any special access to their thoughts, and communicates no more information than normal speech would.

Formians operate from a shared hive intelligence that allows them to communicate nearly instantaneously. While within telepathic range of at least one other formian from the same hive mind, a formian worker gains a +2 circumstance bonus to initiative checks, Perception checks, and saving throws against mental effects. If one formian is aware of a combatant, all members of the hive mind within range are aware of it.

30 feet. Formian mageslayers are surrounded by an aura of disruptive energy that disperses magical energy and makes spellcasting difficult for their enemies. Whenever an enemy creature within the aura attempts to Cast a Spell or Activate a magic item, they must roll a DC 5 flat; on a failed check, the spell or activation is lost and the action is wasted. Free action activations disrupted by this aura can't be attempted again until the start of the activating creature's next turn.

Trigger A creature within the formian mageslayer's disrupting aura that the formian mageslayer can see succeeds at a DC 5 flat to Cast the Spell in the aura Effect The mageslayer attempts to unravel the spell's magic and attempts to counteract the spell. They use their Arcana modifier as their counteract modifier with a counteract rank of 8. If the formian mageslayer succeeds, they counter the spell and use the dispersed energy to gain a number of temporary Hit Points equal to twice the spell's rank for 1 minute. If the formian mageslayer critically fails this counteract check, their disrupting aura deactivates for 1 minute.

A formian mageslayer takes 15 fewer damage from any arcane or primal spell that causes damage, and 10 less damage from any divine or occult spell that causes damage.

A creature damaged by a mageslayer's claw Strike must succeed at a DC 37 will save. The creature becomes Stupefied 2 for 1 round on a failure. On a critical failure, the creature is stupefied 2 for 1 hour.
