The following guide will help any warrior assuming they at least have Rare lvl 80 gear or higher. I will assume you know the basics of this fight, else I encourage you to read this article: http://dulfy.net/2013/08/06/gw2-queens-gauntlet-guide/#12
Weapons:
Only 1 set really needed, Sword and Shield. Here is the skill breakdown:
Sever Artery > Best friend for tagging mobs (will explain further) as well as killing Liadri as bleeding bypasses weakness. Now the easiest set of armor would clearly be carrion, but I managed in berserker’s.
Savage Leap > Assuming you have Auto-targeting removed, using this will help you reach safe zones in Phase 2
Final Thrust > For damage, not really used.
Shield Bash > same as Savage Leap
Shield Stance > Your bread and butter. Use this if your stuck in Shadowfall Circles or to absorb Visions of Mortality you wanna get rid of, your choice!
Utility:
Healing Signet > Rely on the passive healing to keep you afloat. Personaly, I never activate it.
Endure Pain > Use this to take on ShadowFall Circles or to let Liadri beat retaliation into herself! (assuming retaliation proced) WARNING will NOT work on Vision of Mortality! They WILL down you!
Shake it Off > Your best friend in phase 2, either allow you to roll or walk normally. In the case you have full Soldiers Runes, you can clear both conditions off! (I didnt need soldiers)
Signet of Stamina > Allows you to roll much more without the need for Vigor. Use it in situations where you are desperate to remove conditions (especially if she has stacked bleeds on you!)
Signet of Rage > Run of the mill speed boost in most cases, use when possible.
Traits:
Strength > 0
Arms > 30
II > Speed on Crit
III > Increased bleed duration
XI > Incase you need a boost near the end
Defense > 30
IV > Now this rally business may seem silly, but this is a key factor. If you strike Visions of Mortality before they explode on you, you will be downed and rallied instantly. With this trait active, you will be placed at 50% HP with full endurance by doing just that! This can be used as a quick heal, and you are also immune the first second of rally, use ALL of this to your advantage. Just make sure to watch your death penalty as abusing this too often will eventually lead to your demise.
VIII > Block out some of those pesky orb pulls automatically, make sure you destroy them when you get the chance!
XII > Great help to damage her without fighting her directly. Take advantage of the fact that while blocking and under the effects of Endure Pain, she will still be hurt by retaliation, so feel free to pop either to allow her to beat herself up. Also note that if an orb pulls you while retaliation is active, the orb will be destroyed.
Tactics > 0
Discipline > 10
III > Your going to need the extra speed!
Strategy
At this point, you just need to use the above tactics to your advantage, there’s not much else besides knowing the mechanics to help yourself out. I do believe this build allows for the easiest way of pulling it off. Some last minute tips would be to not get crystal greedy (as in popping out crystals even tho death is coming), clear mobs of Visions when you need to make a grab, and don’t be too crazy when your aiming (usualy she will be in melee range anyway).
This being said, I wish you all good luck, and welcome questions/comments. You can either post here for more info or reach me ingame (Char name> Gorva)
