Rage Vortex Berserker Ascendancy, Bandits, and Pantheon Powers
Ascendancy (Marauder – Berserker)
- Crave the Slaughter
- War Bringer
- Flawless Savagery
- Rite of Ruin
Crave the Slaughter provides an insane amount of damage in the form of additional rage generation and maximum rage.
War Bringer, most importantly, provides us with the ability to obtain infinite rage, when combined with 
Redblade Banner. Once you’ve gotten this node and the shield, you can switch your main-link to 
Rage Vortex.
Flawless Savagery provides an insane damage increase, considering our frequency to crit.
Rite of Ruin is saved for last, as it comes with a hefty downside. The degen it will cause is NOT counter-acted by this builds innate life regeneration and is something you have to be aware of. Having 
Enduring Cry on our left-click to constantly trigger, will keep you more than healthy, however.
Bandits
You should kill all since the two passive skill points are more powerful than any of the benefits bandits offer.
However, if this is your first character of the league, it is usually worthwhile to help Alira instead, to get the free resistances and Mana recovery, as they’re a lot harder to get reliably for your first character. You can then switch out to the kill all reward later on, using the vendor recipe.
Pantheons
Major: Soul of Lunaris is a great Pantheon choice for the build, as it provides important Movement Speed along with additional Physical damage mitigation.
Minor: Soul of Shakari – chaos damage reduction is always a good addition to a build, before you get your “Divine Flesh” endgame option. Other minor gods can be chosen depending on personal preference, they aren’t really strong enough to matter in a big way.
Pantheon powers can be upgraded by using 
Divine Vessel in the Map Device while you are activating the particular Map that contains the boss you need. Once you’ve killed the boss and captured his soul, you need to deliver the vessel to Sin in Oriath.
If you’ve beaten the Sirus encounter already, you will have to go back to any town in act 6-10 to talk to Sin, as he doesn’t exist in the new Epilogue town.
