Lieutenant Buldoral  

This mob needs quite a bit of Arcane resists. Investing in Brellium jewellery to get above 13k resists would be a good move.

To fight this mob, there is a ring event. By stepping off the platform, a group of epic mobs will spawn and will need to be killed to spawn the next wave. Use these mobs as a chance to postion the raid.

The next wave will be the Lieutenant, along with another group of the mobs you just killed. Burn adds before the named.

The Lieutenant has an AoE knockback, an AoE arcane and will need to be interrupted every so often. The AoE arcane is easily dealt with if you get 13k+ resists. Every so often, the mob will emote in red text. Someone must harvest a book found in one of the nearby alcoves and use it on him to disrupt this. If you tank him in one of the alcoves, this makes it alot easier.

Apart from that, tank and spank, gratz on your gloves.
