Updated September 18, 2026
If you're about to finish Act 1: City of the Dead in Warcraft III Reforged: Forsaken Kingdom, there are a few things worth checking before you push into Act 2.
Not everything below is a confirmed permanent missable. Some are specific progression risks, while others are optional rewards, Talent Points, or choices you may want to resolve before moving forward.
The two biggest warnings are The Plague Must Flow and Relic Raiders. Players have reported progression problems if the sewer reservoir event is triggered before accepting The Plague Must Flow, or if they leave the Arcane Sanctuary after activating its Energy Generator before completing the puzzle.
Use the checklist below before making the final push out of Act 1.

What Is Actually Missable in Act 1?
Act 1 is City of the Dead, followed by Act 2: A Scarlet Flame. The campaign's Act 1 contains a mixture of main objectives, optional quests, rewards, and side activities.
The important distinction is that not every optional activity is proven to become permanently unavailable when Act 2 begins.
Reported Progression Risks
Two Act 1 activities deserve extra caution because players have reported progression problems.
The Plague Must Flow
Triggering the sewer reservoir sequence before properly accepting the quest can cause the objective to become impossible to complete later.
Relic Raiders
Players have reported an Arcane Sanctuary issue involving the Energy Generator. Leaving the area after activating the generator can leave the portal or puzzle in a state where the quest cannot be completed normally.
These are reported progression issues rather than proof that every Act 1 side quest disappears when you enter Act 2.
Important Completion Targets
Before moving on, it is also worth checking that you have completed the optional content that matters to your run:
- Highway Robbery
- Widow's Lair
- Relic Raiders
- Silverpine Sprint
- Intelligent Behavior
- Gordo
Optional Choices and Story Content
There are also optional quests where the main reason to complete them is the story, a choice, or a useful item:
- Keep an Eye Out
- Pain Beyond Death
- From Many, One
If a quest, reward, or choice matters to your completion of Act 1, finish it before starting the final Act 1 push rather than assuming you'll be able to return later.
The Plague Must Flow: Accept It Before the Reservoir
The Plague Must Flow is one of the most important Act 1 quests to handle carefully.
The objective is straightforward: poison the water reservoir and return to Sylvanas.
The problem is the order in which you interact with the reservoir.
A player report on the official Warcraft III forums describes an issue where entering the sewer's back-right room, solving the circular lever puzzle, and triggering the poison/water sequence before properly receiving The Plague Must Flow can prevent the quest from being completed later.
Safe Order for The Plague Must Flow
To avoid the reported progression problem:
- Accept The Plague Must Flow first.
- Travel to the reservoir.
- Complete the required sewer and lever sequence.
- Trigger the reservoir event.
- Return to Sylvanas and complete the quest.
Quick tip: Accept The Plague Must Flow before triggering the reservoir sequence.
The quest itself has a worthwhile item reward: Seal of Sylvanas, a Rare trinket that provides +5% Ability Vamp and +3 Agility.
This is a specific progression issue, not proof that all Act 1 quests automatically disappear once Act 2 starts.
Relic Raiders: Finish the Arcane Sanctuary Puzzle
Relic Raiders is another Act 1 quest where it is safer to finish the entire sequence in one visit.
The quest asks you to:
- Find an entrance to the Arcane Sanctuary.
- Retrieve the Artifact.
- Return the Artifact to Lexington Mortaim.
The Arcane Sanctuary contains a multi-step puzzle involving the Energy Generator and the portal mechanism.
Players have reported a bug where interacting with the Energy Generator and then leaving the area can cause the generator to become non-interactive when they return. In reported cases, the portal remains closed and the quest can become stuck.
Safe Order for Relic Raiders
Before entering the Arcane Sanctuary:
- Make a manual save.
- Enter the Arcane Sanctuary.
- Activate the Energy Generator.
- Continue through the mechanism rather than leaving the area midway.
- Complete the portal/puzzle sequence.
- Retrieve the Artifact.
- Return it to Lexington Mortaim.
If you are already inside the sanctuary and have started the mechanism, it is safer to complete the puzzle before exploring elsewhere.
For the full puzzle route, see the Warcraft III Reforged Relic Raiders Guide: Arcane Sanctuary Puzzle, Artifact & Reward.
Collect the 3 Act 1 Talent Points
Three Act 1 optional quests have confirmed Talent Point rewards:
If you've completed all three, you've collected the three confirmed Talent Point rewards from these Act 1 optional quests.
Highway Robbery
Highway Robbery asks you to recover Glix's stolen wares from a gnoll camp southwest of the area.
Completing the quest awards 1 Talent Point.
The Huge Flail, Zombie Arm and Agus's Shambling Hand are separate loot rather than the Talent Point reward itself.
Widow's Lair
Widow's Lair takes you into a spider-infested cavern west of the Trade Quarter.
The objective is to defeat the Spider Broodmother.
Completing the quest awards 1 Talent Point.
The Webweaver's Gloves are associated loot, while the Talent Point is the confirmed quest reward.
Relic Raiders
Relic Raiders takes you into the Arcane Sanctuary in the Capital City Ruins.
Completing the quest awards 1 Talent Point.
The Artifact itself is a quest item rather than a combat equipment reward.
Don't Forget Silverpine Sprint
Silverpine Sprint is another optional activity that is easy to overlook because it is separate from the main progression.
The objectives are:
- Travel to Silverpine Forest.
- Complete the race.
- Return to Glix for your reward.
The confirmed completion reward is:
- 300 Gold
- Gnomish Engineering Goggles
The Gnomish Engineering Goggles are Rare Head Armor with:
- +20% Ability Speed
- +40 Movement Speed
- +5 Intelligence
The race is worth checking before leaving Act 1 even if you are not trying to complete every optional activity.
It is not confirmed as a hard permanent missable, so the important point is simply not to overlook it if you want its reward.
Resolve the Edric's Eye Choice
Keep an Eye Out gives you a choice rather than simply handing you a fixed reward.
The quest asks you to find Edric Hollowgaze's lost eye.
Once you recover it, you can choose whether to:
- Return the eye to Edric.
- Keep the eye for yourself.
If you keep it, you receive Edric's Eye, a Common Trinket with the Forsaken Gaze ability.
Forsaken Gaze:
- Reveals the target.
- Reduces the target's Armor by 2 for 30 seconds.
- Has a 30-second cooldown.
If you want the item, make the choice before moving on.
For the full choice breakdown, see the Warcraft III Reforged Keep an Eye Out Guide: Where to Find Edric's Eye & Should You Keep It?
Other Optional Quests to Finish
Several other Act 1 quests are worth checking before you leave the area.
Intelligent Behavior
Intelligent Behavior involves three unusual ghouls:
- The Industrious Ghoul
- The Studious Ghoul
- The Foraging Ghoul
Each one requires a different interaction rather than simply defeating it.
The confirmed rewards include:
- 300 Gold
- Infectious Ghoul Charm
The Infectious Ghoul Charm is a Rare Trinket that can summon Infectious Ghouls.
For the complete route, see the Warcraft III Reforged Intelligent Behavior Guide: All 3 Ghouls, Book Puzzle & Reward.
Gordo
The Gordo quest asks you to find Gordo and free him from the spider guarding him before returning to Melisara.
The main benefit is access to Gordo as a vendor who can buy and sell items.
If you want the additional merchant access during Act 1, complete this quest before moving on.
Pain Beyond Death
Pain Beyond Death asks you to calm the hostile banshees and ultimately deal with Kaelystia.
The quest also contributes to the developing story around Anya and the Forsaken.
Story reward only — no unique item confirmed.
From Many, One
From Many, One sends you after several targets, including the Bandit Lord, Alliance Remnants and the remains of the Grand Marshal.
It is another optional story-focused quest.
No unique item or Talent Point reward is confirmed.
Should You Farm or Upgrade Before Act 2?
Before leaving Act 1, it is worth taking a moment to prepare your heroes rather than immediately pushing into the next act.
A community guide notes that some creeps can respawn between sections, allowing additional farming, and that money carries forward. The same guide recommends preparing before the final Act 1 section because Act 2 begins with a mission where you cannot revive.
Treat that as a player recommendation rather than a formal rule, but the preparation itself is useful.
Before Act 2, Check:
- Spend or save your Gold deliberately.
- Upgrade useful equipment.
- Sell items you no longer need.
- Spend available Talent Points.
- Check your abilities.
- Organize your inventory.
- Finish the optional quests you actually want.
- Make a manual save before the final push.
If you're carrying useful gear from optional quests, make sure it is equipped or safely stored before advancing.

What Changes When Act 2 Begins?
Act 1 is City of the Dead, and the next main act is A Scarlet Flame.
The transition is therefore a natural checkpoint for your Act 1 preparation.
However, it is important not to overstate the situation by saying that every optional quest automatically becomes permanently unavailable when Act 2 begins.
The safer approach is simple:
If you care about an Act 1 quest, reward or choice, finish it before moving on.
That removes the need to determine later whether a particular piece of optional content remains accessible.

FAQ
What should I finish before Act 2 in Forsaken Kingdom?
At minimum, check The Plague Must Flow, Relic Raiders, the three confirmed Talent Point quests, Silverpine Sprint, Intelligent Behavior, Gordo, and any optional choices or story quests you want to complete.
Can The Plague Must Flow become impossible to complete?
A player report describes a progression issue when the reservoir sequence is triggered before the quest is properly accepted. To avoid the problem, accept The Plague Must Flow before interacting with the reservoir sequence.
Can the Arcane Sanctuary quest get stuck?
Players have reported an issue involving the Energy Generator where leaving the Arcane Sanctuary after activating it can leave the mechanism or portal in an unusable state. Making a manual save and completing the sequence in one visit is the safer approach.
How many Talent Points can I get from the confirmed Act 1 optional quests?
Three confirmed Talent Point rewards are associated with Highway Robbery, Widow's Lair and Relic Raiders, for a total of 3 confirmed Talent Points from those quests.
Should I finish Silverpine Sprint before leaving Act 1?
If you want its confirmed rewards, yes. The quest awards 300 Gold and Gnomish Engineering Goggles, making it an easy optional activity to check off before moving forward.
Final Thoughts
You do not need to complete every piece of optional content to progress through Forsaken Kingdom.
But Act 1 is a good place to slow down and clean up your quest log before moving into A Scarlet Flame.
The most important precautions are the two reported progression risks: accept The Plague Must Flow before triggering its reservoir sequence, and finish the Arcane Sanctuary sequence rather than leaving after activating the Energy Generator.
After that, check your three Talent Point quests, collect the Silverpine Sprint and Intelligent Behavior rewards, resolve Edric's Eye if you care about the choice, and make sure your equipment and inventory are ready.
Once that checklist is clear, you're ready to move on from Act 1.
