Abilities & Strategy
Overview
Ula'tek splashes venom across her platform with Caustic Waves. Any Blightscale Spawn that touch her venom hatches and covers players in a Putrid Membrane. While her slithering children continue to spawn, Ula'tek uses her Spectral Coils to shatter the space. After Ula'tek rails against her prison with Rage of the Shackled she summons her faithful then dives beneath the venom to gather her strength. Ula'tek's Doomscale Wardens move between the Blightscale Spawn imbuing them with Writhing Gestation as the Doomscale Eggs begin to hatch. With her progeny broken, Ula'tek shatters the arena. She continues to use Call of the Serpent to gather her forces while destroying the only safe spaces remaining with Circling Prey.
