How to Beat Gortash in BG3: Complete Wyrm's Rock Boss Guide

Preparation: Disable the Steel Watch

BEFORE fighting Gortash: go to the Steel Watch Foundry (Lower City docks). Fight through the foundry, disable the central control, then fight the Steel Watch Titan boss. This deactivates all Steel Watch in the city, dramatically reducing Gortash’s defenses.

Wyrm’s Rock Fortress

After disabling the Steel Watch, return to Wyrm’s Rock. Gortash will be in his quarters on the upper floor. His traps are disabled (because you broke the Steel Watch). The fight is much more manageable now.

Gortash Boss Strategy

Gortash has ~250 HP and is supported by traps and grenades.

Key Mechanics

• Grenade Launchers: Gortash throws multiple grenades per turn. Spread out your party to avoid AoE damage.
• Reflectoguard: Gortash can reflect projectiles. Use melee attacks instead of ranged.
• Traps: The room has floor traps. Disarm them or avoid those tiles.
• Bane’s Fist: His melee attack hits hard. Keep your tank on him.

Strategy

1. Spread out your party (grenades hurt clusters)
2. Cast Hold Person (he has +3 WIS save — not great odds but worth trying)
3. Focus Gortash with melee attacks (avoid ranged due to Reflectoguard)
4. Use Divine Smite, Action Surge, and high-damage spells

After the Fight

Loot Gortash’s Netherstone (required for the final battle). His body also holds the key to his safe, which contains unique items.
