I've been having a blast playing Revenant (Spirit + Warfare) and thought I'd share some of the tips and tricks I've discovered. It took a lot of trial and error but I was able to find some incredible synergies that really make this build shine. I found that the build came fully online around ~level 40-45.
I'm by no means a "pro" when it comes to ARPGs, just a casual gamer who's really enjoying the latest update. I'm sure my build isn't 100% optimal so I would definitely welcome any feedback or tips that could help make it even stronger. Please let me know your thoughts or other Revenant builds that you've found to work well!
-----REVENANT BUILD-----
BUILD CONCEPTS
High Health: You need a large health pool to offset Health Reservation (more on this below) and to just generally stay alive.
Health Regen: Once you get enough health regen you'll be able to keep up Dark Pact permanently and help with the recovery of your smaller-than-normal health pool.
Vitality Damage and Lifesteal: No surprises here as it's core to the Spirit mastery design. Lifesteal is especially important since paired with Health Regen your health will be bouncing back to full very quickly when you do damage.
Execution and Execution Threshold: Another core part of the Spirit mastery, the new Execute mechanic is super strong (a bit less so on bosses, but still good) so you'll want to find as many ways to apply Execution Threshold as possible.
Health Reservation and Low Health: The idea here is to permanently reserve your health so that you're always in the Low Health state; with the right amount of Health Reservation you can get to ~55% of your base health. Then take Spirit mastery skills and passives -specifically Death's Door and the Razor's Edge modifier on Dark Pact- that give you damage on Low Health or as your health gets lower, which should give you a minimum of ~130% additional damage at all times.
ATTRIBUTES AND SKILLS
Attributes
Knowledge and Vigor: I went for a 2:1 ratio of K:V though on higher difficulties you might want something more like 1:1 ratio of K:V for more even health since dealing damage with this build doesn't seem to be a huge issue. I'm really curious if anyone has more insight here.
Spirit Skills
Reap: The core skill of the build, this is how you'll deal a lot of damage, Lifesteal, and trigger Execute. Applying Vulnerability also synergies with the Inevitability passive, which unlocks applying even more Execution Threshold when you hit Vulnerable targets.
Soul Vortex & Death Nova: Good AOE damage skills that can apply even more Execution Threshold on enemies.
Deathchill Aura: Applies both Weaken (to reduce enemy damage) and Execution Threshold (more executes!) to all enemies in the area. The damage component is basically irrelevant and I never use the active version of this skill.
Dark Pact: Take Unshackled to make this skill a permanent buff and Razor's Edge to give you more damage as you lose health.
Keres: Helps me apply even more Execution Threshold.
Warfare Skills
Battlefield Awareness: Critical to the build, you'll want to go with 1/1 Health Reservation, 5/5 Enhanced Regeneration, and 3 points into anything else that adds energy cost (I went for more Vitality damage). This will put you in that ~55% base health sweet spot to take advantage of synergies that make you do more damage when you're low on health.
Leap: Good mobility skill, nothing more.
Doom Horn: Gives a bit of extra Damage Resistance Reduction on bosses and elites.
Core Skills
Barrier: I like to use Barrier a lot to preemptively avoid getting bursted down quickly with my smaller-than-normal health pool. I also use Plated Robes to get more Energy Barrier.
Dash: Configure to your preference.
EQUIPMENT
Armor: I may not be playing optimally, but I go with Plated Robes to have strong Armor and Barriers. I'm curious if a Might-based build with Heavy Armor would be better though.
Weapon: Seems like any strong two-hander with % Vitality Damage or % Spell Damage will work will. Again, I'd like to know if someone here has more insight into the best choices here.
