Trigger A creature targets the blarghest with a hostile action

Effect The blarghest rolls its eyes and sighs, imposing a deep sense of... blargh... upon the attacker. The attacker must attempt a DC 18 Will save; on a failure, it decides its action is too much work and the triggering action is lost. On a critical failure, the creature is also overcome with lethargy, becoming Stunned until the start of its next turn

Speed 15 feet
Melee Jaws +11 (unarmed, unholy), Damage 1d8+4 piercing
Melee Claw +11 (agile, unarmed, unholy), Damage 1d6+4 slashing
Divine Innate Spells DC 18, attack +10; 1st Charm, Command; Cantrips (1st) Message, Prestidigitation
Consider Shape (concentrate, mental)

The blarghest thinks about taking on the shape of a goblinoid (a goblin, hobgoblin, or bugbear) or a wolf, but it ultimately decides that actually doing so is too much work.

Placeholder

The blarghest shouts "Blargh!" to produce the effects of any cantrip that has a verbal component. This action gains the traits of that spell
