Venomous Coiler

Finish Vaults of Atal'Utek: Certain Doom, track Assault the Vault, and enter through 43.72,44.19, 31.29,64.18, or 45.67, 64.90 on Coiled Isle map 2512. The meta is long-term; check each child achievement after its event rotates.

For Roll the Patrol, finish all twelve named patrols: Broken Bonds, Slay the Restless, Slay Children of Ula'tek, Siphon Venom, Scavenged Weapons, Breath and Bile, Congealed Venom, Dragged Below, Vengeance for the Dead, Ash to Ash, Calming the Dead, and Laid to Rest. Pro Poison Patroller's 250-patrol grind is separate and is not required by this meta.

For Spike the Strike, finish Purifying Earth and Sky, Ruuk'jar's Clutch, The Underbelly, Profane Pyres, Overflowing Venom, and Cursed Depths. For Submerge the Incursion, finish Cache of the Three, Supplies Must Flow, and Summoning Ritual.

For Oppose the Foes, defeat Congealed Malice, Khu'tulak, and Susarikk. These are the three named ancient foes; the similarly placed Underbelly targets belong to a different child achievement.

First obtain persistent credit for Szarith the Fanged and Vserix the Sneaky, which can appear outside the strike. Then be present at the start of one Underbelly Temple Strike and tag Champion of the Scale, Priest of the First Rattle, and Guardian of the Sacrifice in that same strike. Current live behavior resets those three strike targets if the event ends incomplete, so do not arrive after the group has killed the Champion.

For Ritual Behavior, deliver Petrified Egg, Venomous Ooze, and Spirit Urn during Summoning Ritual. For Dance While Everyone Watches, use /dance while defending Many Faces Stone, Stone of Shackles, and Poison Stone in Cache of the Three. For A Lone Wanderer, collect one large wandering Soul Globe during Purifying Earth and Sky.

For The Honored Dead, interact with all twelve inscriptions: To a daughter, lover, parents, dream, captain, sons, failure, father, sister, comrades, stranger, and shield-bearer. Keep the achievement tracked while moving through the Vault because they are spread across its interior.

Complete Vaults of Atal'Utek: One Coin Too Many to unlock Er'inye's Corrode Spirit exchange. Buy all fourteen available Spirit Corrosion points for a cumulative 97,500 Corrosive Coins. Costs rise from 1,000 to 20, 000; coins alone stop at fourteen and cannot finish Fully Corroded.

Reach Zul'jarra's Forces Renown 8 and complete the Spirit Corrosion quest from Jan'sari the Watchful, then reach Renown 14 and complete More Spirit Corrosion. These two points are mandatory, so Fully Corroded cannot be completed before the Renown 14 gate even with excess coins.

Obtain and complete the questlines started by Lost Med'jai Amulet, Eye of Szarith, Feather of Tok'jara, and Mummified Lynx's Paw. Each unlocks one of the Altar's four choice nodes and supplies one Spirit Corrosion point. Confirm all four node locks are removed before spending the final points.

Return to the Altar and allocate the fourteen coin points, two Renown points, and four relic points across every node, including the second ranks in the last row. Fully Corroded tracks 20 talents unlocked; owning unspent Spirit Corrosion does not complete the criterion.

Verify all ten child achievements—Roll the Patrol, Spike the Strike, Submerge the Incursion, Oppose the Foes, A Lone Wanderer, Dance While Everyone Watches, Ritual Behavior, Soft Underbelly, The Honored Dead, Fully Corroded. The completed meta awards Venomous Coiler directly.
