Broader Gameplay Benefits

Breaks up monotony by adding badly needed boss diversity in Diablo 4 Items the Greater tier.
Justifies more build experimentation, as players would need resistances/mechanics tuned to Elias, not just poison/physical for Duriel.
Injects fresh lore relevance into Season 9 without building a boss from scratch.
Gives Necromancer and caster fans a strong thematic opponent while expanding on the Horadrim betrayal story.

Lore Justification: Elias Isn't Finished

Elias's entire arc in the campaign revolves around his immortality, obsession with Lilith, and twisted desire to reshape Sanctuary under the Triune's teachings. Players only temporarily cripple him - never truly destroy him. He must reconstitute somewhere, plotting revenge as he rebuilds his magical arsenal. Lore hints suggest Elias can only be permanently slain if his original Horadric sigil is shattered, something the player never confirms doing.

This makes Elias' reappearance not just sensible - it fills in story gaps and builds hype for Diablo 4's 2026 expansion (where the Horadrim storyline is expected to explode again).

Final Verdict: Elevate Elias Immediately

With Diablo 4 firing on all cylinders in Season 9, now is the perfect time for Blizzard to capitalize on their momentum by expanding one of the game's most successful new systems - the Lair Boss ladder. Elias is a lore-rich, mechanically appropriate, and already developed boss who could refresh endgame flow with minimal lift.

Diablo 4 Season 9 Endgame Guide: Hyperspeed Teleport Necromancer 

"Speed is power… but infinite teleportation is godhood."

If you thought Necromancers were slow-paced summoners skulking behind skeletal walls - think again. With the launch of Season 9: Sins of the Horadrim, a bizarre and likely unintended interaction between two Horadric Powers has unlocked one of the fastest builds ever seen in Diablo 4 history: the Hyperspeed Teleport Necromancer.

Combining reckless glitch abuse with elite-tier dungeon clearing potential, this build lets you permanently teleport across the map, shred enemies with curses and scaling damage, and, if paired with the right Diablo 4 Items, annihilate every farming route faster than any Sorcerer Blink, Rogue Dash, or Druid Lunge ever could.

Concept Overview - What Makes Teleport Infinity Possible?

At the heart of this monstrosity is the interaction between two Horadric Powers introduced in Season 9:

Cosmic Anomaly: Randomly spawns cosmic rifts that trigger various effects.
Floating Bubble: Occasionally spawns an orb that grants a blink-like teleport when walked into - complete with a 4-second cooldown.

Individually, these are nothing special. However, when paired - and then forced into a glitch state via animation canceling and insane Attack Speed breakpoints - they allow your Necromancer to enter and exit Floating Bubbles faster than the game can register the cooldown. The moment the two powers' animation lock, you gain infinite instant-cast teleports, letting you traverse the game at cheap Diablo 4 gold a ludicrous pace.
