Before engaging, make sure everyone has some form of Levitation as Tallon Zek has a Gravity Flux. Also be sure to pull and kill the trash mobs out of the the corners of his room prior to having the raid enter.

Tallon Zek is pretty straight forward, but has a few mechanics to note:

1. He will chain cast Barb of Tallon. This Spell has 4 different types of effects:
Targeted AE, -300 HP DoT/-150 AC/60% Deaggro on Main Tank, -100 Disease Based)
Targeted AE, 1500-3500 DD, -100 Cold Based, 40% Slow, 40% Snare
Single Target, 3500 DD, -100 Fire Based, 5 second recast)
Single Target, 1750 DD, -100 Poison Based)

2. Shadowsteps around the room, facing different directions.

3. Gravity Fluxes frequently, especially on the tank.

4. Casts a PBAE dispel. Bury your levitate buff as much as you can. If it gets dispelled get another one if needed.

5. Casts Tallon’s Balance: PBAE -300 Resist Debuff

6. Melees for about 1,000 at most. His melee is weak and he has a low amount of HP.

The general strategy is that this is a ranged only fight  due to his constant shadowsteping and frontal cone with a damage/slow/snare effect, but you can certainly have melee go in to do some extra damage. You can still  try to have some tanks on him, but aggro will bounce around. The main reason a raid would wipe is if everyone got AE’d down by his cone and/or didn’t have levitate. Overall the fight is trivial.

Keep the tanks up, Load AE heals, and have the raid spread out so not everyone gets hit at once by his AE.
