FAQ

What are Ether Quests in Hero Siege?
Ether Quests are the quest chain connected to the Ether Tree system that Season 10 expanded with roughly a hundred new nodes. Completing the quest line is how most players drive their Ether progression through the Ebontharn update.
When should I start Ether Quests?
Community guidance puts the start in the endgame onboarding window — after the campaign, as you climb the upper difficulty ladder. The quest objectives assume a level 100 character with a working build rather than a campaign-era one.
Do Ether Quests expire during the season?
The quest line persists for the season — there is no documented expiration mid-season. What does change is the surrounding balance: 7.0.x patches have touched Ether-adjacent nodes and systems, so check current patch notes before planning long sessions around a specific objective.

How Do Ether Quests Work?

Ether Quests are the bridge between playing the game and powering the Ether Tree — the progression layer Season 10 expanded by about a hundred nodes. The chain presents objectives across the endgame, and completing them feeds the Ether progression that keeps paying out for the rest of the season. Unlike a one-time reward, the value compounds: every node the chain unlocks makes your build permanently better at the content the next objective asks for.

When Should You Start the Chain?

The practical start signal, consistent across guides: campaign finished, level 100, first endgame build assembled. The objectives are tuned for characters already working through the upper difficulty ladder — starting earlier mostly produces frustration, and the rewards mean little to a build that is still transitioning.

That placement is deliberate design, and it mirrors how the Incarnation Tree was introduced in Season 9: long-system progression unlocks when the player has a build worth investing in.

The Completion Order That Works

Documented runs of the chain converge on the same shape:

  1. Pick up the chain early in your endgame routine — the first objectives double as a tour of the systems you should already be touching: endgame zones, farming routes, boss content.
  2. Batch objectives with your farming loop. The chain is designed to be completed alongside normal endgame play, not instead of it — players who detour to quest objectives exclusively lose the farming income that funds the rest of the season.
  3. Feed everything into the tree, not the market. Ether progression is account-season power; early market temptations are cheaper to satisfy with gold farming than with stalled quest chains.
  4. Re-check after every patch. The 7.0.x line has already touched Ether-adjacent systems — the patch tracker lists what moved.

What Ether Progression Actually Buys

The reason the chain matters is the tree it feeds. Season 10’s Ether expansion turned the system into one of the largest long-term power sources in the game — comparable in scale to the Incarnation Tree rollout that defined Season 9 — and the community’s endgame builds assume the nodes are flowing. A completed or progressing Ether Tree shows up in three places:

  • Clear speed — offensive nodes compound with your build’s core scaling.
  • Farming efficiency — faster clears convert directly into gold and drop volume.
  • Endgame access — the top of the Uber roster and deep wormhole pushes assume endgame-level character power, of which the Ether Tree is a major slice.

Ether Quests FAQ

Can I complete Ether Quests on any difficulty?

The objectives track endgame content, which lives in the upper ladder. Community guidance is to progress the chain alongside your natural difficulty climb rather than farming it at a tier your build outgrew.

Do I need a specific class for the chain?

No. The chain is class-agnostic, though clear speed varies across the tier list as always — faster builds finish objective-heavy stretches sooner.

What if an objective seems impossible?

Check three things, in order: whether a 7.0.x patch changed the requirement (the patch tracker), whether your build is under-geared for the objective’s tier, and whether the community has documented a route trick. If all three fail, the chain will still be there after your build catches up — it is a season-long system, not a race.
