Up to 5-20% Strength based on the charge time of your heavy attacks. Stacks 3 times.
12-24% Rending on Enemy Weak Spot Hit for 3.5s. Stacks 5 times.
Target receives up to 2-8 Stacks of 2.5% Brittleness, scaling with charge time of Secondary Attack. Debuff lasts for 5 seconds and can have a maximum of 16 stacks.
-8.5--5.5% Charge Time on Chained Secondary Attack. Stacks 3 times.
Empyrhic resolve (-40% peril) is the star here.. Keep spamming Voidblasts till your teammates need to go to therapy for shell shock. Also allows you to stay in high peril for 20% dmg buff.
You do, have to stay close to the team due to your ass toughness replenishment. The good thing is that you can stagger any elite and rager (save for nurgle blessing) and support any frontliner DPS with brittleness stacks. You will mostly be operating under bubble shield due to its toughness regen that you lack. With the selected talents on maelstrom/auric. It is very easy to score 4 warp charges with your kill potential (not even needing to use brain rupture in most cases) and to have another bubble shield up before the duration of the active one ends. The extra 2 talent node is unnecessary as you aren't lacking damage with Voidblast/trauma stave as you won't be hitting any new breakpoints with elites. Its whole purpose is to have 100% uptime on bubble Sanctuary.
Staple Blessings
Melee: Force Sword
Deflector mandatory. Due to lack of toughness regen, and a method to get out of hairy situations.
Stave: Voidblast
Warp Flurry mandatory. As you will be running many fully charged blasts to stagger melee specials and elites.
Rending Shockwave. Mandatory for this build, but i think a few tweaks can land this in other variations of this build
Alternate talent selection:
You can run a more brain burst centric version of this, using empowered tree. The five points after Empyhric resolve just go into empowered tree. I reconmend running shield barriers to more leverage brain rupture use. Its just less reliable due to the RNG nature of empowered psionics.
Kinetic Deflection for Puppet Master. Increased coherency to maximize vampiric aura and gain warp charges.
Extremely good for melee only and poxburster squads modifier for Auric Maelstrom.
