Notes

To edit these notes, go to Template:K'zrath, Plague Lord of Madness notes.

  • As a Plague Lord boss:
    • If the player loses against a Plague Lord, its current Health will be its new maximum Health should the player encounter it again.
    • The number of turns is unlimited in this encounter.
    • Plague Lord's Hero Power and deck depend on their current Health.
      • If it is between 201-300, it uses Phase 1's Hero Power and deck.
      • If it is between 101-200, it uses Phase 2's.
      • If it is 100 or below, it uses Phase 3's.
      • During the phase change, the Plague Lord will draw extra cards. Their deck is also completely replaced by a new one.
      • If its Health is "set" by Saviors of UldumFlex-plosion, its Hero Power and deck stay the same until it is damaged by any means.

Release your will. Succumb to the madness!
Your bravado masks your weakness, human. (vs. Reno Jackson)
Your companions look down on you, beast. (vs. Sir Finley)
Genius is just a gateway to madness, elf. (vs. Elise Starseeker)
Your companions are thieves, dwarf. (vs. Brann Bronzebeard)

Anyone who is not you is an enemy.
Friendship is only an illusion. It is easily shattered.
None have fought beside you without thinking of fighting against you.
I began as anxiety, turned to dread, grew into fright, and matured into madness.
Great minds are undone by the smallest questions.
Jealousy and paranoia are my playthings. Also crossword puzzles.
