Saurian Worldwatcher

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.

Frequency once per round Trigger A creature makes a melee Strike against the worldwatcher but misses Effect The worldwatcher breaks the triggering creature's limb or weapon. If the triggering Strike was an unarmed attack, the triggering creature takes 6d6 bludgeoning damage and becomes Clumsy 1 until the limb is reset (an Interact action with the manipulate trait). If the triggering Strike was a weapon Strike, the weapon takes 6d6 bludgeoning damage.

The saurian worldwatcher bellows, evoking the power of the primordial world. Non-dinosaur creatures within 30-foot emanation take 10d6 sonic damage (DC 38 fortitude save). On a failed save, a creature is also Slowed 2 for 1 round (Stunned 1d4 on a critical failure). The saurian can't use Boneshaking Roar again for 1d4 rounds.

Whenever the worldwatcher hits a creature with their fist or naginata Strike, that creature must succeed at a DC 39 fortitude save or be Stunned 1 (Stunned 3 on a critical hit).
