Boss Skills:
Line Drive: Causes stun/faint status and knockdown players, may instant kill someone who took full hits.
Death Claw: 4 directions.
Red Wave (~40 sec CD): Knock back and knock down players. Red wave emanates from the Death Knight in a fan-shaped manner. After a few seconds, the area covered by the red waves will explode and deal huge damage. The direction in which he cast this, cannot be altered with provoke (Meaning he might not aim at the Paladin).
To avoid this attack, quickly move out of the fan-shaped AoE when you see the red waves. Damage can be reduced with damage reduction skills but cannot be evaded with evasion skills. (Evasion Slash etc)
