BG3 Gortash Boss Fight: Disable the Steelwatch First (Turret Sequence + Honour Mode Guide)

Verified against BG3 Patch 8 (June 2026, final content patch). Honour Mode values may change with future hotfixes.

Most players find Gortash at his coronation surrounded by nine Steel Watchers, a fully-trapped Audience Hall, and Flaming Fist guards. Fighting him there is the fight the game wants you to lose. The actual strategy is to leave, gut his mechanical army at the Steel Watch Foundry, pre-destroy his throne room buff devices in stealth, and walk back in for a fight that is four turns instead of fourteen. This guide covers the exact foundry sequence, what Gortash does on turn 1 that most guides skip, and how Honour Mode changes the entire damage economy.

Quick Start Checklist

1. Complete the Iron Throne rescue — saves Duke Ravengard and prevents his scripted death during the Gortash encounter
2. Attend the coronation and agree not to kill Gortash — keeps all five dependent Act 3 quest chains intact
3. Complete Disable the Steel Watch at the foundry (steps below) — removes every Steel Watcher from his fight and rewards Gontr Mael
4. Enter Gortash’s throne room in turn-based stealth and destroy all Micromodron Force Curtains before initiating dialogue
5. Cast Greater Invisibility on your highest-burst striker before combat — sets up a guaranteed Surprise Round

When NOT to attempt: Below level 9 on Balanced or level 10 in Honour Mode, your burst window may not push him past 75% HP before his Phase 2 temporary HP resets the board. Also critical: killing Gortash before the Steel Watch Foundry quest causes the Elder Brain to seize control of the Steel Watch and destroy the foundry automatically — permanently losing Gontr Mael from the run.

The Steel Watch Turret Disable Sequence

Steel Watchers have +6 Initiative. With nine of them in the throne room, your first two rounds of every fight go toward constructs instead of Gortash. Completing the Disable the Steel Watch quest removes every one of them before the encounter begins — Gortash alone without his mechanical army is a different fight entirely.

The Steel Watch Foundry sits in the southwest corner of the Lower City near the Grey Harbour waypoint. A Steel Watcher patrols the entrance — lockpick the front gate and time your entry so it is on the western side of its patrol route.

Order of operations inside matters:

1. Save the Gondians first. When the submersible docks you have eight turns to free all Gondian workers from their cells before the timer expires. Do this before engaging anything at the Neurocitor. Destroying the Neurocitor with Gondians still in their cells kills every one of them — and loses you Zanner Toobin’s assistance.
2. Defeat the Steel Watcher Titan. This is the mandatory mid-foundry combat. If you rescued Wulbren in Act 2 and told Zanner his daughter is safe, Zanner accompanies you and destroys the Neurocitor after the Titan dies — the cleanest path through.
3. Destroy the Neurocitor using whichever method applies to your run:
   • Zanner’s assistance — available if the Gondians are rescued and Zanner’s daughter was freed from the submersible during Act 2
   • Runepowder Bomb — requires Wulbren’s Act 2 rescue. Interact with the Neurocitor with the bomb in your inventory, select the dialogue option to place it, move your entire party to a safe distance, then detonate
   • Speak with Dead — cast on Zanner’s corpse if he died during the fight; he gives you the destruction code
   • The books method — read both “Property of Zanner Toobin” and “The Many Faces of Gond.” Gond’s true name, Nebelun, is the unlock phrase for the Neurocitor and works without any companion assistance

The Steel Watcher Titan drops Gontr Mael, a legendary longbow and one of the strongest ranged weapons in Act 3. Killing Gortash first — in any order — causes the Elder Brain to destroy the foundry, removing this weapon permanently. Complete the foundry before returning to Wyrm’s Rock.

Gortash’s Trap Activation Pattern — What Happens the Moment Combat Starts

On his first turn, Gortash moves toward the entrance doors. As he does, the Micromodron Force Curtains mounted along the perimeter walls fire within their 18-meter range, applying Shell of Resistance — granting him immunity to Thunder damage, resistance to all elemental damage, an extra bonus action, and an additional 3 meters of movement speed for one turn. This triggers before most parties can act, and the curtains recharge every round they survive.

The critical distinction almost every guide misses: there are two types of Force Curtain in this room, and they do opposite things.

Micromodron Force Curtain stats: HP 8, Sturdy condition (requires a single hit of 10 or more damage to register). Vulnerable to Bludgeoning and Lightning. Immune to Thunder, Fire, Psychic, Poison. A Lightning-charged melee swing or one cast of Chain Lightning destroys multiple curtains simultaneously — Chain Lightning is the most efficient option since it jumps between targets and can clear the entire cluster in a single 3rd-level slot.

Use the pre-combat window. Enter the throne room in turn-based stealth before initiating any dialogue with Gortash. Move your Sorcerer or Wizard to range and cast Chain Lightning to sweep the Micromodron curtains. Any character who can deal 10+ Bludgeoning or Lightning damage works on individual curtains. Once all Micromodron curtains are gone, Gortash receives no Shell of Resistance regardless of his movement pattern — his AC drops back to 16 base and his action economy normalizes.

The Deranged Force Curtains flicker erratically and are visually distinct from the functioning ones. They impose negative effects when active. Do not destroy them.

Also during this pre-combat scouting phase: the Grenade Impellers and Incineration Casters near the entrance doors deal AoE damage to anyone in range — including Gortash if he walks through them. You can destroy them before combat (Bludgeoning/Lightning again), or position your party away from that corridor and let Gortash trigger them himself when he moves. A Fog Cloud placed over the door zone prevents him from using that path at all.

Combat Phase 1: Surprise Round Setup and Initiative

In Honour Mode, Gortash rolls Initiative with a +10 modifier. Without countermeasures, he acts first every round, generates Shell of Resistance from surviving curtains, and fires Dazzling Ray (2d10 Radiant + Blind on a failed DEX save) into your backline before you can respond. The Surprise Round is the primary tool for bypassing this.

A Surprised creature cannot take Actions or Reactions for the entire first round of combat. To reliably surprise Gortash:

• Cast Greater Invisibility on your highest-burst striker before initiating combat — Invisible characters break line of sight, so Gortash cannot detect them and becomes Surprised when the fight starts
• Use the Elixir of Vigilance on party members you want to protect from being Surprised themselves when other enemies in the room initiate
• The Alert feat, Feral Instinct, and Elixir of Vigilance grant Surprise immunity — if Gortash were to have these in any difficulty variant, confirm before committing to a pure stealth approach

A Gloomstalker 5 / Assassin 4 striker using this setup gets two Assassinate attacks with automatic critical hits against the Surprised target. Testing this composition against Gortash on Honour Mode consistently pushes him past 75% HP damage before he acts — reducing Phase 2 to the only real challenge remaining.

One class-specific hazard to know before committing to a pure ranged opener: Gortash has a Reflectoguard passive that can bounce projectiles and arrows back at the attacker. Melee strikers and spell casters are immune to this. If your primary damage dealer is an archer, shift to spells or melee for this encounter, or confirm via in-game testing whether Reflectoguard is active on your difficulty before the pull.

Turn 1 priority after your Surprise Round attacks:

1. Destroy any surviving Micromodron Force Curtains if pre-combat scouting was incomplete
2. Cast Fog Cloud or Darkness onto Gortash’s position — all enemies here rely on line of sight, and removing it prevents Dazzling Ray and reduces his effective movement targets
3. Eliminate Black Gauntlet mages (Command and Dominate Person can remove party members from the fight for multiple rounds)

Build-specific Phase 1 approach:

Honour Mode: Tyrannical Branding and Legendary Resistance

On Balanced and Tactician, Gortash is a burst target once his defenses are stripped. Honour Mode adds two mechanics that change how you distribute attacks across the fight.

Tyrannical Branding (Legendary Action, 1/round): After any attack that hits Gortash, he can immediately Brand the attacker as a reactive Legendary Action — at no cost to his normal turn. The Brand applies escalating pressure to whichever character keeps swinging at him. The counter is attacker rotation: a different party member strikes him each round so no one accumulates stacked Brands. Summons from Animate Dead or Conjure Animals are more efficient — they absorb the Brand while your real damage dealers swing unreacted. For the specific summon compositions that work best for this approach, see our party compositions guide.

Legendary Resistance (3 uses/round, +10 each): Each use adds +10 to his next saving throw. Stack multiple save-based spells per round to burn through all three charges quickly. A Divination Wizard with pre-loaded Portent dice (a 1 or 2 from the previous long rest) can force a total of 11 or 12 at most on the d20 contribution (Portent’s die plus Legendary Resistance’s +10) — against high-DC conditions like Stunning Strike, this still fails even when combined with his full save modifier, making Portent the most reliable tool for landing CC through his Legendary Resistance.

Stunning Strike is the highest-value single action in Honour Mode: A Monk who lands Stunning Strike (CON save DC = 8 + proficiency bonus + WIS modifier) removes Gortash’s ability to use Legendary Actions while he is Stunned. One successful Stun costs him a full round of legendary economy. Buff your Monk with Elixir of Alertness for advantage on attack rolls before pulling, then open with Ki points on the Stun attempt before committing to regular strikes.

Note from the Honour Mode tips guide: Gortash retains the ability to use Legendary Actions even while blinded, so Fog Cloud does not shut down Tyrannical Branding — it only prevents Dazzling Ray and reduces his positional options.

Phase 2: Invoke the Black Hand

When Gortash drops below 75% of his Balanced HP — below approximately 207 HP — he triggers Invoke the Black Hand mid-round: 150 temporary hit points fill his bar, and he enters Avatar of Tyranny form. This happens before your next action if he goes at any point in the initiative order, which is why Surprise-bursting past the threshold before he acts is the cleanest way to handle it.

Phase 2 imposes two adjustments:

• New immunities: Thunder, Fire, and Force damage no longer register on top of his existing Thunder resistance. Drop Call Lightning, Fireball, and Force-typed spells immediately. Switch to Necrotic, Cold, Psychic, or Radiant — Inflict Wounds, Ray of Frost, and Dissonant Whispers all cut through his Phase 2 profile cleanly.
• The Closed Fist of Bane: His unarmed melee attack in Avatar of Tyranny form deals Force damage. Keep fragile party members at range. Misty Step or Dimension Door are the clean repositioning options — Thunderstep wastes a Thunder damage instance that now does nothing.

The 150 temporary hit points deplete as he takes damage. A party that maintained consistent DPS output before the threshold trigger burns through them in two to three rounds. The danger is overcorrecting — stopping to reposition the entire party in response to the HP reset instead of continuing to apply pressure through the transition.

Frequently Asked Questions

Can you kill Gortash at his coronation?

Technically yes, but it is one of the worst decisions available in Act 3. You face him alongside nine Steel Watchers, Flaming Fist guards, and a fully-armed trap corridor. More consequentially, attacking during the coronation breaks at least five quest chains — including Stop the Presses and the entire Gondian sequence — permanently locking out Gontr Mael and several ally options for the final fight. Attend, decline any hostile option, and return after the foundry.

What happens if you kill Gortash before Orin?

Nothing blocks completion — they can die in any order. The story handles both sequences. The only practical consequence is that killing Gortash before the Steel Watch Foundry quest causes the Elder Brain to seize the Steel Watch network and destroy the foundry, skipping the quest entirely and removing Gontr Mael from the playthrough permanently.

Can the Rhapsody Dagger be pre-stacked before this fight?

Yes — Gortash is a valid kill target for Scarlet Remittance attribution. Pre-stack the kill counter on weaker enemies in the throne room (or in earlier encounters) before focusing him, so your Rogue enters the Phase 2 burst window with the full bonus already loaded. See our Rhapsody Dagger guide for the exact staging positions across the Act 3 boss sequence.

What does Gortash drop?

The Netherstone-Studded Gauntlet — containing his Netherstone, one of three required to confront the Elder Brain at the Morphic Pool — is the mandatory drop that gates Act 3 completion. He also drops the Fabricated Arbalest (his Dazzling Ray crossbow), Cloth of Authority (+1 AC, immunity to Frightened), and Tyrannical Jackboots.

Conclusion

Gortash rewards preparation more than raw damage. Disabling the Steel Watch removes his nine highest-initiative allies before you enter the room. Destroying the Micromodron Force Curtains in stealth prevents Shell of Resistance from activating before your party acts. Guaranteeing a Surprise Round gives you a free burst window against a boss whose +10 Honour Mode initiative would otherwise put him at the top of every initiative order.

In Honour Mode, the fight reduces to three problems: spreading your attacks so Tyrannical Branding never stacks on one character, burning through Legendary Resistance with layered save spells before landing CC, and pushing past 75% HP before he acts to reach Phase 2 on your terms. For the full Act 3 context — including how the order you approach Gortash and Orin affects quest outcomes and the finale — see our BG3 Act 3 Guide.
