Hell Eternal
The basic mechanics of the Story Mode version of Hell Eternal. Useful to take into Elite 1 - 4 as a basis of what to expect as far as moves go! I can confirm that these mechanics are much the same in Elite 1, just much less forgiving.
Archaean Seismocratist: None of his casts can be interrupted. He casts Shadow in the Blood on the tank, which is a large AoE which can damage anyone else who stands in it and explodes after a few seconds. He’ll also cast a large AoE Caldera which if it hits anyone, they get knocked back and take 3 stacks of Corrupted. He’ll also Flame Lash the highest damaging target, which pulls them toward him and knocks them down.
Lustrehunter: The scardey-cat demon with all the eyes shields himself with Occluding Lens which needs to be purged; it is a reflect shield. He’ll also periodically Fallback, stunning everyone while he runs away, and buff himself.
Prime Maker: It starts off with a reflect shield which needs to be removed by dragging it through water puddles. As flames come out of the center of the forge, it gains “Heat” 10 stacks at a time; at 100 stacks of “Heat” its shield goes back up. Reduction is interruptible and Corrupts the tank; standing in the flame wisps will stack Corrupted FAST. The wisps can’t be killed and tend to trail behind the golem, so staying in front of him is a good idea. Its other casts, which cannot be interrupted, are Carburising Flame, an AoE that spawns under player feet, and Furnace Blast, a large AoE around the golem.
Flagillatrix Superior: She needs to be taken to the left and then, if the fight lasts that long, turned at the intersection. She casts Spitelance, which can be interrupted but also gets her to move forward really fast so can be used to position her, Vigil, which sets off yellow alert alarms that are alarmingly LOUD and make her Piston Predators and Mortar Monstrosity move faster. If her Tyrants get close to the party, the Mortar Monstrosities will cast Firmament Barrage, causing a number of red tracking reticles to chase people, while the Piston Predators cast a large AoE Earthen Revolt.
The three Hadean Guards: All of them can cast Painwheel Overdrive, an interruptible AoE, but won’t until one has been killed.
The Iscariot, Hadean Guard: She casts uninterruptible Immolation Invocation on the player doing the most damage, which will burn them as they stand unless they run around trailing damaging fire after them. If she is the last left alive, she will cast Shadow in the Blood on the tank while continuing to cast Immolation Invocation.
Brutus, Hadean Guard: He regularly shields his companions with Black Iron Bulwark, which can’t be purged or interrupted. If he is the last alive, he casts Body Hammer, which can’t be interrupted but can be dodged; first he tries to stun and damage the tank, then turns onto another player to charge at them.
Cassius, Hadean Guard: She normally casts Chirurgy, an interruptible heal for herself or one of her allies. If she’s the last alive, she will shield herself in Metallic Purity, a reflect shield that can be purged.
Eblis, Dominus Inferni In Profundis: Eblis will Solar Collapse putting giant red AoE nearby that turn into semi-persistent fire hazards. Because of this, he should be kept to the edges of the area. He’ll often Dark Rush, dropping Shadow in the Blood on everyone he dashes through. Ideally, this should only be the tank, and because backing against a wall won’t stop his dash, it’s better to keep him out in the open where the tank can back up away from the rest of the party which is going to be eagerly chasing Eblis. Shadow in the Blood can do a lot of damage to someone who steps in it, even killing them. For this reason, it’s a good idea for melee DPS and the tank not to be all crammed up on top of Eblis.
He’ll also occasionally stun someone with Consummation, which sucks down a lot of their HP and stuns them (and Eblis) for a short time.
Eblis will Cast Out two or three times during the fight, yanking everyone into a bubble full of moving ground AoE periodically; while in the bubble, he’ll cast Painwheel Overdrive, which can be interrupted, and Vanquish, two column attacks that blast from his wings, which can’t. If he also attacks the tank, it’s the last Cast Out. Damaging him enough in disco bubble phase will either cause him to Cast Out everyone into the normal Hell, or he’ll die.
