Dagoom the Sea King: how players beat Queen's Domain's first big wall

Quick answer

Dagoom the Sea King is the boss at the end of Obmuer Temple, after the Trident Keys. His whirlpool, knockbacks and overlapping poison phases can cover the arena, and he has a lot of health. Players who beat him agree on three things: use the wind dash constantly, since it works with any weapon, repositions you out of the poison and deals damage; kill the fish adds with a Splash Hammer or a fully charged secondary; and if he still walls you, explore elsewhere first for levels, heals and throwables. Patches 1.01.02 and 1.01.03 fixed his death bugs; the fight itself is unchanged.

Where he is

Obmuer Temple opens with four Triangular Slates; the Trident Keys open its inner doors and Dagoom waits at the end. Gamer Guides' route reaches him at 4:58 and Gamer Social Club's launch-day footage shows the fight, both bound to the progress route.

What players who beat him did

Eishern's complaint is the one most players share: knockbacks, arena-wide stuns and two poison phases that overlap. The replies are consistent that the fight is about movement and health, not a trick.

Expect small adds on the arena floor (a Toxic Serf bar appears) while Dagoom attacks; keep moving and deal with them.

  1. Dash, all the time: the wind dash works with any weapon, moves you out of the poison pools and the whirlpool, and hurts enemies you dash through.
  2. Kill the fish adds fast: a Splash Hammer, or a secondary with its charge bar full, drops them.
  3. Still stuck? Leave the temple, level up elsewhere and come back with more heals, throwables and a better amulet.
