Underkeep dungeon guide

Dungeon quick facts

In the waning days of the old kingdom, the people of Alexandria sought a way to survive as their home sank beneath the earth. They built a towering structure that enveloped the royal castle itself, and as the long years came and went, Everkeep grew to soaring heights. Yet some whisper that the castle has withstood the ravages of time, and in the city's foundation endures as a symbol of bygone glory. From within those timeworn depths Calyx sends his transmissions, and you must delve into Alexandria's past to ascertain their source.

Boss and mechanic notes

Underkeep has local boss notes for: Gargant, Soldier S0, Indefatigable Defense: Valia Pira. These notes are pulled from the local wiki and should be treated as source-backed prep unless separately marked as human-reviewed strategy.

• Chilling Chirp: Party-wide magical damage.
• Almighty Racket: The boss will face a random player and use a late telegraphed 180 degree frontal cleave. Get behind.
• The boss will then become untargetable, jump outside the arena, and begin crawling around. Take note of its location, as the sand falls will obscure it. When it stops (always behind a sand fall), it will re-emerge and use a late telegraphed wide line AoE charge (Aerial Assault) through the arena.
• AoE combinations
• Chilling Chirp will now summon two circle AoE telegraphs on opposite cardinals.
• Almighty Racket: Get behind.
• Three circle AoE telegraphs will then appear along with spread marker AoEs on each player (Sedimentary Debris) dealing magical damage. Spread out in the safe zone.
• Earthsong: Spawns two sets of untargetable Sand Sphere adds, each of which will use a telegraphed point-blank AoE (Sphere Shatter). The first set has 7 spheres and the second set has 6. The boss will jump outside again and being moving around, so players will need to keep track of its location while dodging the AoEs.
• Almighty Racket + Sedimentary Debris
• Trap Jaws: Telegraphed physical tankbuster.
• Field of Scorn: Party-wide magical damage.
• Thunderous Slash: Telegraphed magical tankbuster.
• Sector Bisector: The boss will brandish its glowing sword to its left or right, while a small purple wave of energy will appear at its feet on that side. It will then spawn six linked clones of itself in a hexagon, all with the same animation. The clones will then begin disappearing in a clockwise or counterclockwise pattern. The last clone to disappear will emit a half-room cleave from its location based on which side is glowing.
• Ordered Fire: Spawns four untargetable Add Blocks in pairs outside of the arena. These will use a late telegraphed line AoE in front of them, leaving one quadrant of the arena safe. At the same time, the boss will cast Static Force, placing conal spread markers on everyone, so they should spread out in the safe quadrant. The spread resolve shortly after the line AoEs, so there is time to adjust back into the previously unsafe areas for more space.
