The Serpent's Nest

A 6-12 player Veil instance for levels 126-150: dragon-haunted tunnels, the Elder Nest Tree and the Shadow of the Serpent.

Updated 4 October 2026instance12-manpartyLv126-150
Below Nidhoggur's old nest, the Veil keeps a brood of its own. Clear the tunnels, cut down the tree that feeds on the Veil, and face the Shadow of the Serpent.
It works like Echoes of Glast Heim: the party leader forms the run at the Veil Muster, members enter there, monsters grow with the party, the fallen are raised after 60 seconds (except before the final boss), and every boss leaves a Veil Spoils chest.

The four stages

  1. Upper tunnels:
    Nest Draco
    ,
    Nest Pinguicula
    ,
    Nest Aqua Elemental
    .
  2. Deep tunnels:
    Nest Red Ferus
    ,
    Nest Green Ferus
    ,
    Nest Gold Acidus
    ,
    Nest Blue Acidus
    .
  3. West cavern:
    Nest Rata
    ,
    Nest Duneyrr
    and the mid-boss
    Elder Nest Tree
    . At half health it calls the nest's creatures to its roots.
  4. East cavern:
    Shadow of the Serpent
    .
    • At half health it calls the brood.
    • At 20 % health it enrages (35 % with the Enraged affix).
    • Every 30 seconds it spits venom at a random player: 2.5 seconds later a pool bursts where they stood, for 30 % of max HP to everyone within 3 cells. Step out of it, and keep apart so one pool never catches several of you. It never kills on its own.

Rewards

Once a week per character:
  • 400 Hunting Coin (through the daily Hunting Coin cap)
  • 1 Veil Essence II (account-bound)
  • 1 Shadow Cache (account-bound)
  • 2 Enriched Elunium or Enriched Oridecon
  • Heroic adds 100 more Hunting Coins.
Your week starts at the first boss you see fall, exactly as in Echoes of Glast Heim. A quest in your quest window, "[Veil] The Serpent's Nest: weekly clear", shows it. Characters above Lv160 help without rewards or rolls.
Rare extra: the final chest holds a Mental Expansion Ring in about 15 % of runs, rolled with Need, Greed or Pass like the other spoils. No monster or shop on ArionRO offers it anywhere else.
