You can easily parkour past the initial invisible wall and get out of the dungeon, then glide to the last boss!

Items used:

• Wearing: Onyx Amulet with Wind Sculpting Stone & Harmonic Music Stone, 3x Azerite Armor with the Longstrider trait, Scroll of Momentum, speed enchants
• Before entering: Fried Bonefish, Charged Phial of Alacrity
• During run: Flexweave Underlay, Nitro Boosts, Quickwick Candlestick

The current WR by Maximillium uses a lag macro speed-up strategy which does not seem to work for me in any instance, though I have heard reports of it still working.
