Avenge the Drowned BG3 Guide

Embark on a gripping side quest in Baldur’s Gate 3 Act 3 that intertwines vengeance, stealth, and critical timing. The Avenge the Drowned mission challenges players to balance revenge for a drowned priestess with major story objectives, offering unique rewards and combat opportunities.

Quest Origins and Initiation

The quest unfolds in the bustling Lower City, drawing players into the watery cult of Umberlee. Head to the southwestern edge near the Steel Watch Foundry to the Water Queen’s House, a somber site of mourning. Here, Flood Tide Allandra Grey leads a ritual over her sister’s submerged remains, blaming a mechanical beast from the depths.

To start, approach Diomira Trellis at the entrance and engage without dismissing the proceedings. Proceed inside and speak to Allandra, who demands tribute. Offer your combat prowess instead—select options like pledging to slay the beast. She reveals the ‘metal monster’ as a submersible craft and tasks you with eliminating its dwarven controller.

• Enter Water Queen’s House via Lower City southwest corner.
• Speak to Diomira; choose non-dismissive dialogue.
• Interact with Allandra; avoid ‘no tribute’ options initially.
• Pledge aid: ‘I’m good at slaying beasts’ or similar.

This activates the journal entry, directing you to trace oily trails from the harbor leading to Flymm Cargo across the water.

Navigating to Flymm Cargo: Stealth and Entry Methods

Flymm Cargo looms as a guarded warehouse teeming with feral worgs and hidden dangers. Positioned directly across the harbor, access it by circling north to avoid patrols. Stealth is paramount—rooftop infiltration provides the safest entry.

Key approaches include:

• Rooftop Jump: Scale the east side roof, dash south, and leap to the fire escape from the southwest corner. Lockpick the door (DC 20 Sleight of Hand).
• Front Doors: Lockpick double metal doors (DC 20), but triggers worg aggression immediately.
• Sewer Bypass: From Lower City Sewers near grease mephits, climb a greasy grate for a creature-free path.

Inside, clear worg packs methodically. Descend to the basement via crates at coordinates roughly X: -164 Y: -141, shoving obstacles aside.

Confronting Redhammer: Choices and Consequences

Redhammer, the Deviser dwarf, pilots the submersible tied to Gortash’s Iron Throne prison—crucial for Save the Gondians and Rescue the Grand Duke quests. Poor timing can lock out progress, so sequence matters.

Optimal path: Chat to extract Iron Throne info, end dialogue, assassinate post-long rest to clear Gondians. Pilot manually if needed.

Quest Flow: Ideal Timing with Main Story

Integrate seamlessly to avoid conflicts. Perform after initial Allandra meet but before Steel Watch destruction, preserving NPCs.

1. Initiate with Allandra at Water Queen’s House.
2. Locate Redhammer; coax Iron Throne mention.
3. Terminate talk; eliminate him (stealth recommended).
4. Long rest; access submersible to Iron Throne for rescues.
5. Report success to Allandra for closure.

Post-Iron Throne, Allandra may demand handover—refusal sparks ambush with cultists hurling ice and summoning elementals. Banish works on watery foes.

Combat Tactics for Key Encounters

Flymm Cargo worgs favor packs; use range and crowd control. Basement guards employ nets and ice—prioritize leaders.

Cult ambush post-choice: Position high ground, dispel terror auras, target summoners first. Steel Watch ties demand crystal management—destroy post-commander kills to safeguard Gondians.

• Worgs: Area denial spells; ranged focus.
• Cultists: Anti-magic for summons; banishment viable.
• Crystal Fights: Rush commanders; intel save on activation.

Rewards and Loot Highlights

Success yields the Wavemother’s Robe: boosts swim speed, cold resistance, and Umberlee spellcasting—ideal for aquatic builds. Additional cargo loot includes rights and camp dialogues enhancing ties.

Quest completion advances Umberlee faction subtly, opening niche interactions without major alignment shifts.

Common Pitfalls and Troubleshooting

Avoid premature kills pre-Iron Throne—Redhammer vanishes in submersible. No Gondians during assassination via long rest. Sewer skip evades beasts entirely.

If locked out: Reload save; sequence post-Gondian rescue but pre-foundry raid.

Advanced Strategies for Multiple Completions

Honor mode demands precision: Pre-buff stealth, single-target bursts on Redhammer. Multi-quest weaving maximizes efficiency, saving travel.

Roleplay variants: Merciless slayer for evil runs; warning for neutral, preserving Iron Throne access longer.
