Gasping Aura (air, aura, divine, transmutation) 100 feet. Creatures within the aura must succeed at a DC 37 Fortitude save. On a failure, they can't breathe and must hold their breath to avoid suffocation until they leave the aura. The tumblak can activate or deactivate the aura with a single free action, which has the concentrate trait.

No Breath Tumblaks don't need to breathe.

Claustrophobic Nightmares (curse, divine, enchantment, mental) A creature fatigued by the tumblak's nightmare spell is subject to paralyzing glimpses of being buried alive. Anyone using an effect that would remove the fatigued condition through a means other than a full night's rest must succeed on a DC 44 counteract check or the fatigued condition isn't removed. When the fatigued creature enters a stressful situation, such as rolling initiative in combat or entering a high-stakes negotiation, it is affected by Stoutaern Echoes.

Stoutaern Echoes (divine, emotion, enchantment, incapacitation, mental) A creature struck by the tumblak's fist or impacted by Claustrophobic Nightmares must succeed on a DC 44 Will save or feel itself confined on all sides. The creature is immobilized and flat-footed until it Escapes (DC 44).
