Nalorakk - Bear Avatar

It is a 2-Phase fight:

First phase - Human form:

He does a random charge.
Mangle - Increases damage done by bleeds by 100%.

Second phase - Bear form:

Applies 2 different bleed effects.
Raid wide Silence - 4-5 seconds long, does approx 1k damage.

Phase 1 is simply tank and spank. Make sure to heal the random person charged.

Phase 2 have the 2nd tank taunt the boss and be careful of the cleave so make sure the raid is not next to where the 2nd tank is bringing the boss.

When he goes back to human form, have the first tank taunt it, repeat until he is dead.

After this boss you can take your pick at targetting any of the 3 next Avatars first but in terms of difficulty they are listed below.

For the time quest the kill order would logically be: Bear, Eagle, Dragonhawk, Lynx, Malacrass and finally Zul'Jin.
