Gravelight Sentry

The Gravelight Sentry is a watcher found in the Imperial City Prison, located on an island surrounded by toxic water.(map) It serves as the dungeon's second mini-boss, together with the five Xivkyn Necromancers around it.

The Twitching Eyeball lead for the Mora's Whispers mythic pauldron can be obtained by defeating the Gravelight Sentry and its attendant necromancers.

Skills and Abilities

As a boss type creature, the Gravelight Sentry is immune to all crowd control effects.

Gaze

The watcher shoots a beam from its eye directly at the player as a basic ranged attack. It does moderate magic damage.

Doom-Truth's Gaze

The watcher winds up and releases a series of beams along the ground in front of it. Getting hit by one will do high magical damage to the player, and stun them briefly. The beams can be avoided by being behind the watcher when it is performing this attack.

Shockwave

The boss spins around releasing a burst of magic as indicated by the large red circle. Any players hit will take moderate magical damage and will be knocked back. The Gravelight Sentry's version of Shockwave is much larger than usual and will throw players away much further, usually into the toxic water. Roll dodge or sprint to quickly escape the water.

Corrupt Water

The water around the island is toxic and will do high poison damage over time to players standing in it. When enraged, the Gravelight Sentry will summon blobs of poison from the water that will land on the player's location, dealing moderate poison damage and stunning them as indicated by red circles. Keep moving to avoid this. Do note that the stun from this attack and the frequency at which it is performed will make it almost impossible to resurrect any dead players once the boss is enraged, so be careful not to die here.

Summon Venomous Skeleton

The Xivkyn Necromancers will channel a spell that will summon a Venomous Skeleton to attack the party if completed. This can be interrupted. Killing the necromancer will also cause all the skeletons it summoned to immediately die.

Enrage

When three Xivkyn Necromancers are killed, the Gravelight Sentry will glow red and enrage, causing the special version of Corrupt Water to activate as described above.

Notes

• The usual strategy for dealing with this encounter is to kill all the Xivkyn Necromancers first before killing the Gravelight Sentry. This is because leaving the necromancers alive will cause more adds to be summoned, which can be overwhelming for groups with lower damage. Even though killing the necromancers will cause the Gravelight Sentry to enrage, the additional poison attack is easily mitigated by avoiding the red AOEs.
• The Gravelight Sentry and the Necromancers must be defeated together. Wiping before killing all of them will cause the whole group to respawn.

Dialogue

When approaching the boss arena:

Gravelight Sentry: "The intruders are coming, Lord Warden."

Lord Warden Dusk: "You've allowed them far enough. Fail here, and I'll feed you to the Abomination!"

When casting Summon Venomous Skeleton:

Xivkyn Necromancer: "Stand and fight, prisoner! You serve the Lord Warden, now!"

Xivkyn Necromancer: "Rise! Rise and fulfill your new purpose!"

Xivkyn Necromancer: "The Lord Warden calls you to serve, prisoner!"

Xivkyn Necromancer: "Awaken, and fight for your Lord Warden!"

Xivkyn Necromancer: "The Lord Warden grants you another chance at life! Now kill the intruders!"
