The Black Stalker Abilities

1. Chain Lightning will be cast on a random player hitting them for around 2,000 and jumping to nearby party members. The damage after each jump is reduced by 50%.
2. Levitate will put a player in the air, during this ranged dps and healers can still do damage and heal.
3. Static Charge is a nature damage DoT dealing 750 damage a second for 10 seconds.

The Black Stalker Strategy

1. The tank runs in and tanks him in the center of the room. Party members stay a good distance from each other, avoiding the damage of Static Charge and Chain Lightning being spread.
2. Levitate is annoying but ranged dps and healers can still participate while levitated so this is not too much of an issue.
