Great Roar [>>] (evocation, primal, sonic) The slana emits a deafening roar. All creatures within a 100-foot cone take 16d8 sonic damage (DC 44 basic Reflex saving throw). On a failed save, a creature is also deafened for 1 minute and stunned 1 (or deafened permanently and stunned 3 on a critical failure). The slana can't use Great Roar again for 1d4 rounds.

Pounce [>] The slana Strides and makes a Strike at the end of that movement. If the slana began this action hidden, they remain hidden until after the ability's Strike.

Thunder Trap A creature hit by the slana's thunderclap attack is immobilized and held in place by reverberations of sound until it Escapes or Forces Open the bonds of thunder that constrain it (DC 44). The target is deafened as long as it is immobilized by a thunder trap.
