Eldritch Deathlord

The Eldritch deathlord was an undead spirit roaming the coast of Dustwallow Marsh. He was defeated by Rexxar, Cairne Bloodhoof, Chen Stormstout, and Rokhan.

Deathlords are rumored to have once been mighty paladins of the Silver Hand. In life, Eldritch deathlord committed civilian massacres akin to the atrocity committed by Arthas in Stratholme, going as far as murdering his own family. The paladin, now a deathlord revenant, later came to be found on the Echo Isles. His spirit haunted the islands until he was destroyed by Rexxar, Rokhan, and Chen Stormstout, who claimed his shield as it was a powerful weapon.

Eldritch deathlord is probably the most powerful mob ever in Warcraft III and is the only one that is labeled as level 20.

He drops Shield of the Deathlord.

From Warcraft III: The Frozen Throne:

• level 20
• 10000 HP (normal difficulty level) 14000 HP (hard) (+376% or +526% more than a regular Deeplord Revenant)
• 1200 MP (+100% more than a regular Deeplord Revenant)
• 301-308 chaos melee damage (+317% more than a regular Deeplord Revenant)
• 120 heavy armor (+5900% more than a regular Deeplord Revenant)

Note: Eldritch deathlord is being compared to the deeplord revenant which is the most powerful non-unique revenant.
