Soul-Shaking Croak (sonic)

Grouloop utters a powerful croak that deals 6d10 sonic damage to any non-boggard within a 30-foot emanation (DC 27 basic Fortitude save).

A creature with the Frightened condition that fails its saving throw increases its frightened condition by 1 (on a critical failure, the creature is also Fleeing for as long as it is frightened).

Grouloop can't use Soul-Shaking Croak again for 1d4 rounds.

Swamp Stride

Grouloop ignores difficult terrain caused by swamp terrain features.

Tongue Grab

If Grouloop hits a creature with her tongue, that creature becomes Grabbed. Unlike with a normal grab, the creature isn't Immobilized, but it can't move beyond the reach of Grouloop's tongue.

A creature can sever the tongue by hitting AC 24 and dealing at least 9 slashing damage. Though this doesn't deal any damage to the boggard, it prevents her from using her tongue Strike until she regrows her tongue, which takes a week.
