Gearnid - The Flooded Gnomegrad: how to beat

A guide to the whole place: modes, waves and bosses in order. Every boss has its own deck and turn cycle — the numbers come from the game. Loot is in the item atlas and on the Gearnid - The Flooded Gnomegrad page.

In short

• Dungeon, levels 29–38, bosses: 5. Party — 3 heroes: tank, healer, damage dealer.
• Modes: Heroic (at level 60), Normal (at the place’s level, 29–38), Keystone +10 (Mythic+, at level 60).
• Cold — 5 of 5 bosses (on heroic and in keystones); a test strike — every boss, except in normal mode. These modes cannot be cleared without a tank and a healer.
• Normal mode has no cold, no test strikes and no “no tank — through shields” rule.
