Groal the Great
A hard story-required fight in Bilewater — fight #18 of 34 in our complete Silksong boss list.
Groal the Great is the great terror of the Bilewater swamps — an Act 2 story fight where the arena itself is the second boss. Bile Eruption carves hazardous pools across the swamp floor while his Gorge Grab sweeps wide enough to end careless positioning instantly.
This is a ground-control fight. The player who manages the floor wins; the player who only looks at Groal's health bar swims in it.

Eructations of bile carve hazardous pools across the swamp arena.

A sweeping grab that must be dashed through, never jumped.
Strategy
Dash through the grab, never jump it
The Gorge Grab must be dashed through — jumping over it puts you in its rising arc. Build the reflex early: low sweep means dash, not hop.
Track the bile pools
Bile Eruption reshapes the arena every cycle. Ground control matters more than raw damage — fight the urge to chase and instead keep one clean lane of floor between you and the next eruption.
Heal from elevation
Elevated platforms are the only safe Bind windows in this arena. Route your movement so a platform is always one dash away when your health dips.
