Malistaire is the final boss of the Graveyard and he holds the prized gear drops that everyone is after. The minions that spawn each time you face him are random schools. Malistaire will steal any universal blade or shield that is cast and he will remove any universal traps.
There are some exceptions to this rule that are important to note. If you are Balance and cast Bladestorm, he will only take your blade, not everyone’s blade. If someone on the team is over level 100 and has trained Indemnity, a universal trap such as Feint can be cast on this boss. If you are able to protect your blades with Aegis, they will withstand one cheat. Mass Feint will not be removed by Malistaire, and can stack with other traps.
After every fourth round, there will be an Earthquake. My preferred sure-fire strategy for a Wizard with at level gear and stats is as follows. Trap the boss for the first four rounds. Fifth and sixth round stack up some blades, and then hit on round seven or eight. Yes, counting rounds is necessary here.
They call him The Undying because when Malistaire dies the first time, he returns with even more health. It is the ideal strategy to cast Doom and Gloom on the kill round to counter-act this cheat, so be prepared with it in your treasure card deck unless you are the attacker. Ideally, after the boss dies someone lifts the Doom as soon as possible with Sanctuary or even just a school ring such as Darkwind. When Malistaire returns in shadow form, his dragon rebels against him and casts a 100% Feint. This makes killing him the second time that much easier. Use the same strategy as before to send him to the after-life for good this time, and good luck on drops.
