Is the PoE lvl 34 easy to do? I don't have a Gjally but I do have a maxed Icebreaker. I feel like the solar burn is a great opportunity. But I also feel it might be hard because of that.
And PoE lvl 32 too?
The level 34 is much easier than the level 32 imo. Only thing that's troubling is the 4th round which is arguably much harder than the actual Boss. It's Hive with Arc Burn. (Ton of Hallowed Wizards and Knights...)
I'll leave a list of what each boss does and how to get past them.
Urrox, The Flame Prince: Hive Knight, whenever he summons his rage, the floor will burn. Sounds very annoying right? Not really. All you have to do is jump and you won't get damaged. Warlocks and Titans are recommended to use here, though if you have a Hunter, make sure a Defender Titan is on the team, when they pop Ward of Dawn with Blessings of Light or Armor of Light, just jump out and jump back in. Recommended Weapon loadout: Vision of Confluence (Or any Adept Weapons that are solar burn, preferably Scout Rifles or Hand Cannons.), Black Hammer (Or other Solar Snipers that will destroy fast. If no Gally, then Icebreaker is definitely recommended.), and Gjallarhorn (Hunger of Crota is a great alternative.)
Gulrot, The Unclean: This ugly ogre just throws up all over the room and slows you down, like the Fallen mines, but slower. You'll have Worm Keepers that spawn, kill them before unloading on Gulrot. Exposure is active here, so take cover and try to regain health. Recommended Weapon loadout: Vision of Confluence (Or other moderate damage dealing primaries with a moderate rate of fire.), Black Hammer (Icebreaker, Efrideets, other really great damaging snipers.), Gjallarhorn (Again other tracking or Grenades and Horseshoes Rocket Launcher are great alternatives.)
Qodron, Gate Lord: This uncanny machine of hate loves to put you in breakable bubbles, why? Cause they kill you if you don't destroy them! Every now and then you'll have Qodron's Eye spawn, a Major Goblin. Kill it to get the "Jailbreaker" perk for a short time, this allows for you to break your bubble really fast. You also want to huddle with your teammates in order to deal max damage to the bubbles and get out quicker. The modifier active here is Trickle. Try not to use your Supers on... well nothing, unless absolutely needed. Recommended weapon loadout: Fatebringer or Word of Crota, whichever you prefer. Snipers or Shotguns are preferred here, Shotguns for the bubble, which take them out fast. (Found Verdict or fast rate of fire shotguns are best.) The snipers also deal great damage to the shields and can be used to damage Qodron. Gjallarhorn/Truth/Hunger of Crota, Qodron likes to move a lot on the center stage so Truth's aggressive tracking will help a lot here, though Gjallarhorn is preferred more.
Valus Trau'ug: This annoying Cabal Ultra will really make you want to rip your hair out. He changes his shields. To different burns. Make sure you have all three burns in your weapon slots. Recommended loadouts: Fatebringer, Vision of Confluence, Fang of Ir Yut, Word of Crota, any raid Primaries really. Black Hammer, Icebreaker, Patience and Time, Praedyth's Revenge, any raid secondaries. Gjallarhorn, Truth, Thunderlord, any raid heavy weapons.
Kaliks Reborn: This overly annoying Servitor gorges on Ether. Why? It restores health. What better than a boss that regens health?! Archon Servants will spawn and you will want to ignore them for the first 2 times he gorges. There will be a minute to a minute and a half delay of gorging. Just unload on Kaliks right after he gorges the second time. Grounded is active, so stay on your feet. At 50% health he'll spawn a Target that must be eliminated so keep an eye out for him. Recommended Weapon loadout: Fatebringer or Fang of Ir Yut (Other adept arc weapons work too), Black Hammer, Icebreaker, Patience and Time. (High damage dealing secondary snipers, and the occasional Found Verdict for Captains that get too close.) Gjallarhorn/Hunger of Crota/Hezen Vengeance. (High blast radius and damage dealing rocket launchers with Tracking/Grenades and Horseshoes.)
Hopefully this helped!
