Thaumetal Refinery

Thaumetal Refinery is a dungeon, originally for 5-man level 65 parties.

Dungeon is known as "Cyrux Research Facility" in Korea.

Dungeon was released in October 2017 (NA Arsenal / EU Might of the Mechanic patch), same time as RK-9 Kennel and new style level 65 endgame gear. Dungeon also had hard mode.

Dungeon was rereleased in patch 99 in October 2020. It's been converted to 3-man format. Sadly some scenes like mine car travel inside dungeon are removed. 3-man format without healer was horrible shitshow, especially on last boss due constant and heavy AOE with complex and hard-to-dodge patterns, permanent damaging puddles building on dungeon floor, impossibility to move the boss and impossible to dodge exploding goblins. It was soon removed in January 2021 patch.

Dungeon drops collection cards "Gaaruksalk" and "Transgoblification Lab".
