Strategy

Tormentor Urdig has two mechanics that need to be avoided, he alternates using both of them although they can happen at the same time.

Melee players and tanks need to avoid the Large Yellow/Orange rectangle that covers a large area across the boss themself, when the yellow circle under the boss fully charges up to the edge the entire Large Yellow rectangle will deal massive damage for a few seconds.
This can be hard to see on Tatooine and Hoth due to blending into the ground, as it has been pictured above.

All players both melee and ranged need to be careful for Light Blue Lightning circles. Every 30 seconds light blue circles will spawn under 12 random players, you will only have 5 seconds to move before several lightning bolts strike every circle.
Getting hit by one lightning circle will not kill you, getting hit by two or multiple at the same time will.
This can be hard to see on Hoth due to blending into the snow.
