Velik's Sanctuary

Velik’s Sanctuary is a 5-man dungeon for level 68 (originally level 65) players.

Dungeon was released May 2017 as part of Velik’s Fate (Velika's Secrets in EU) patch. Hard mode was out bit later. Hard mode was part of endgame and dropped materials for tier 12 Deathwrack (VM9) gear.

Dungeon was reopened in January 2019, including the hard mode version. VS remained one of the hardest mid-tier dungeons.

On patch 92 in April 2020 it was moved to level 68, where it's lower mid-tier dungeon with 446 ilevel required. Unfortunately, it's still harder than Red Refuge or RK-9 Kennel that require higher ilevel. To compensate devs have given players 99 free resurrects. Dungeon was closed in January 2021 patch v102. Dungeon also has quite entertaining adjustable difficulty version December 2020 to January 2021 that gave lancers Evil God weapon skin and Kalligar partner (along with DA runs).

Note: there are several instances with name "Velik’s Sanctuary". Instance where you talk to Velik during story quest, accessible by talking to priestess and other Velik’s Sanctuary when entering Ghillieglade.

Lore
As seen in Velik's Hold, Lakan is taking over the Velik's Sanctuary. His plan is to create bridge toward Agaia to free Manahan, after Shandra Manaya has failed to do this.

Dungeon bosses are servants of Lakan, who previously had dungeons of their own.

Bosses

 * Revived Darkan
 * Revived Dakuryon
 * Mutated Perimos
 * Lakan

Darkan and Dakuryon are last boss and second boss from Sky Cruiser Endeavor and Shadow Sanguinary, although they have some extra mechanics. Mastering these bosses makes runs much easier. Miniboss Perimos is first boss of Shadow Sanguinary.
