Wyvernlord Tuluun  

This mob is a tank and spank, with one major trick that will require either one player focusing on it, or a raid on the ball.

In the fight, the mob will cast a Black Vision on the player, making them unable to see and fight. Another player has to right click them and use the extra option to guide them to the pool to remove the black vision. By guiding them, they will be teleported to the water, and the effect will be removed. They must them get out the pool quickly (within a few seconds), or adds will spawn.
