Rank 1
Brawler's Guild: Rank 1 - Fight 1 - Bruce
is a crocolisk with jaws that can cut steel, and easily make short work of any player caught in their vicinity. This mangling maw of maliciousness will debuff the player with an instant ability called Powerful Bite which will reduce the armor of the receiving end by 20% for 5 minutes.
He also has a cast ability that absolutely MUST be avoided. It is called Chomp Chomp Chomp which are 3 very quick chomps doing over half a million damage each. When players see this being cast they need to run to the side. Right or left, not backwards or through him to avoid this attack. Anyone who is able to avoid his cast ability should have no trouble with this gator.
Brawler's Guild: Rank 1 - Fight 2 - Vian the Volatile
2,192,281 HP - 19k DPS minimum required to advance.
Vian is a hot-headed Mogu Elemental Shaman that employs fire attacks. He will use an attack called Fire Line which creates a highly damaging column of fire in front of him that can easily be avoided by sidestepping it. He also casts Volatile Flames which either summon balls of fire that can move, or stationary ones that will start to fill up the room if he isn't taken out quickly.
He does use Lava Burst as well, but it should be noted that interrupting his spell casts causes him to melee attack which is more damaging than his spell casts. This should only be done if a player has high mitigation against physical damage.
Brawler's Guild: Rank 1 - Fight 3 - Goredome
is a shoveltusk with a flare in his temper. His most damaging attack is called Lumbering Charge where he makes a red circle on the ground and then charges it, killing anyone in the circle. This attack can be avoided by simply running out of the circle.
Lumbering Charge can also be stunned or interrupted by rooting him before the ability has a chance to charge. He also employs melee attacks but does minimal damage. Other than that he just can be whittled down at a player's leisure.
Brawler's Guild: Rank 1 - Fight 4 - Dungeon Master Vishas
Vishas is a Rogue, once employed by the Scarlet Crusade as a torturer of the their Undead prisoners. Players may remember him as the first boss in the Scarlet Monastery Graveyard dungeon. He uses hot pokers to dole out his penchant for pain. His ability Heated Pokers needs to be avoided at all costs as this buffs his melee attacks and does high amounts of fire damage to anyone in range. Players should use any cc (crowd control) they have available at this point. He can be rooted, stunned, snared or feared during this time, and even possible to slow and outrun him. He also uses a debuff called Naughty Secrets which increases all shadow damage taken by players for 1 minute but this is of minimal concern. Burst him down when he isn't buffed (as his crowd control could break) and he should go down relatively quickly.
