Strategies:
The Ascent: Arbalest as a means to kill the hydras through their shields was primarily the main thing I focused here. Just took my time making solar wells with my grenade to have good uptime on well of life regeneration.
Akelous (Harpy Boss): Similar to the ascent I took my time here proc'ing well of life as often as I could as I went around shooting the nodes. I think a key here for me was clearing the sky of harpy enemies so that they couldn't flinch me off my aim during DPS, especially since I am using a LFR. In terms of how I did DPS, I found trying to get off 3-4 fusion grenades with witherhoard and funnelweb spam was effective for around the first 40-50% of the travel distance the boss makes, then when it becomes too far to accurately throw nades I put in an entire clip of cataclysmic into it. I think if done like this effectively in a phase it's possible to 3 phase this boss, but as seen in my clear I took 4 since all DPS phases weren't as good as the first.
Persys (Wyvern Boss): Same logic as the rest of this dungeon, took my time killing ads and trying to never get cornered or slammed by the boss. I think when the phase starts it's key to quickly eliminate the hydras to spawn the minotaurs in order to quickly get the arctrician buff and shoot the red wires quickly to stop the supplicants spawning. From this point it's just a formality of staying alive, avoiding ads, and taking your time getting the nodes as there is no pressure to be fast if you don't want to be. For DPS itself I tried, note tried, to shoot 1-2 anarchy shots, throw fusion nades on cooldown and spam primary to increase the grenade regen. If I saw the grenade regen going down I would reshoot anarchy again and continue the cycle. If using this DPS strat I personally believe it's a comfortable 5 phase.
Hopefully something above might be helpful if you give this a go, it was a fun one to run. Thanks for stopping by and best of luck!
Loadouts:
Armor and Subclass:
Starfire Protocol with fusion nades, icarus dash and touch of flame aspects for DPS encounters, heat rises over touch of flame for transition encounters. Mods include, elemental ordnance, well of ordnance, elemental time dilation, well of life, weakened clear, and solo operative.
Weapons:
Entrance - ad clearing weapons, I used witherhoard, funnel web, and an LFR to snipe the cyclops
The Ascent - Arbalest, so that I can shoot through the shields of the hydras. Funnelweb, good ad clear, tears through the void shields on the minotaurs. Commemoration, good ad clear, void, useful for bursting ads and supplicants at a longer range than funnel web.
Akelous (Harpy Boss): Witherhoard, good ad clear, procs weakened clear. Funnelweb, good ad clear, good for void shields and shooting eyes on the harpy. Cataclysmic with 4th times and bait & switch for ranged DPS.
The Descent (Transition): witherhoard, funnelweb, and commemoration, overall just need good ad clear here.
Persys (Wyvern Boss): Duty Bound, for ocassional ad clear but mainly for shooting the nodes. Forbearance, primary ad clear, excellent for clearing the rooms quickly. Anarchy, DPS weapon that allows for continuous damage to continue grenade regeneration with starfire protocol.
