Parhelion Plaza Delve Guide: Location, Boss Strategies, and Trash

Parhelion Plaza is a Delve located on the West side of Isle of Quel'Danas.

This guide will provide all the specifics you need to complete the Parhelion Plaza Delve across all tiers of difficulties (from Tier 1 to Tier 11). We will cover Delve events, optional bosses (rares), as well as end of the dungeon boss and their abilities. If you would like to learn about the rest of the Delves in Midnight, please see our overviews linked below.

In this event, you must use a Improvised Arcane Device to traverse void portals, enter Voidstorm areas, and destroy portals. You can only carry the device for 40 seconds at a time, and drop it when entering combat.

In this event, you must help defend Parhelion Plaza against a Devouring Host attack. To help with that you have access to the Tempest Keep legendary weapons - The same ones you've rescued at the start of the main Midnight questline!

You'll also need to rebuild broken barricades as you progress through the Delve.

In this event, you must make use of Quel'Danas Sentinel machines to destroy void pylons around Parhelion Plaza, while killing Devouring Host members in the process. There are plenty of machines scattered throughout the Delve, and they will rush towards the nearest pylon to destroy it.

Gladius Slaurna is the boss of all Delve variants in Parhelion Plaza. He is one of the tougher Delve bosses in Midnight, and can easily overwhelm you. Here is what you have to do to defeat him more easily:

• At the start and then periodically throughout the fight, Slaurna will summon three Sacrificial Voidcaller; these NPCs will spam Void Bolt at you, which MUST be interrupted whenever possible. They have fairly low health so killing them should be priority due to Devouring Nova.
• Devouring Nova doesn't do much besides a knockback on its own, but any Sacrificial Voidcallers still alive at the end of the cast will give Slaurna increased damage done and reduced damage taken.
• Voidscar Raze is easy enough to dodge, just make sure you're not in the line reticle for the spell.
