The Dagannoth mother is fought at the end of the quest Horror from the Deep. She cycles through different colours every 18 seconds to explicitly show her weaknesses.

While fighting the Dagannoth Mother, it is possible to hide or safespot behind the nearby stalagmites. Protect from Missiles is advised as her Ranged attack is highly accurate. She can hit up to 9s with Melee, and can hit double 12s with Ranged. Pures are advised to bring a ring of recoil and turn off auto-retaliate if not using melee.

Note: The twinflame staff cannot be effectively used against her, as even when trying to cast other elemental spells, it will default to casting earth spells due to the Dagannoth mother's elemental weakness to earth.

Once she is defeated, you will obtain a rusty casket.

She can be fought in the Nightmare Zone after the quest is complete. Runes are provided in the arena.
