Dream group (10m) : 2 tanks, 2-3 healers, 5-6 dps

Phase 1

He will cast the following abilities:

•  Tempest Slash : Ta'yak will create a tornado that will move to the designated target and stay there until the end of phase 1. It is recommended that the raid move to get away from the tornadoes when there's too much.
•  Unseen Strike : Ta'yak will place an arrow above a random player. The raid must immediately stack on this person to share the damage between the players. It is impossible to resist/immune this attack. This attack will also send you in a direction for ~20-30 yards, be careful as it might send you into tornadoes.
•  Wind Step : Ta'yak will randomly "shadowstep" to a player and cast this on them. Every player in a 10 yards radius of the affected player will also be affected by this debuff. It is possible to remove the debuff via abilities like  Blessing of Protection
• At 20%, Ta'yak will enter in phase 2.

Phase 2

When phase 2 begins, Ta'yak will gather all the players to one side of the room, while Ta'yak move to the other side. He will then use the following ability.

•  Storm Unleashed : Ta'yak will cast tornadoes that moves towards the opposite side of the room. Players must run towards Ta'yak and dodge the oncoming tornadoes. Players must avoid them at all cost, otherwise they will be sent back behind.

Notes

• During the fight, Ta'yak will be casting  Overwhelming Assault on the tank. The second tank must take aggro right after and so until the debuff wears out.
• Ta'yak will also be gaining stacks of  Intensify during the fight, increasing his damage output.
