I suggest using 5 Crimson Archon Shards with Ability Strength for even more Mesmer Skin etc.

Duration:
Not many tend to mod for ability duration, but it benefits 2 stun time and greatly helps the energy cost on other abilities (thanks to more uptime), it heavily benefits 4 energy drain. If you were to remove [Narrow Minded] and [Primed Continuity], the drain for 4 would be 34 and 68 charged, instead of the current 11 and 22 charged.

Range:
This improves the Width of Reave, allowing you to easier hit more enemies.

Abilities:
It wouldn't be stupid to replace 1 or 4 with Roar (damage) or Terrify (armor strip) subsume, especially against lower-level enemies you could choose to keep ability 1. However, 1 can be useful if you play solo or with players who understands Revenant. If you are facing high-level enemies, you could subsume Roar or Terrify and replace 4, then use 1 and 3 to kill (but then you might as well use my Mind Control build, so you don't have to Enthrall all the time)
^on that note, you probably wouldn't want to use 4 in higher levels, which is why I would suggest replacing that with either Roar, Terrify or Mind Control and sticking to using 1 and 3 to clear enemies. However, all enemies at about level 100 and below will get absolutely destroyed and 4 is a really funny ability to use. Most content you play is probably level 100 or below, let's be honest (unless you enjoy endurance runs.) I prefer keeping 4 on my main build, for the fun factor and the efficiency 4 brings to the table, then having it swapped for higher-level content on a secondary setup with the same mods, etc.

No [Vitality] mod since you get survivability from Mesmer Skin which scales with ability strength.
^Keep that ability up at all times (ability 2)

Arcanes:
Molt Augmented for more Ability Strength throughout the level (this also allows for more Mesmer Skin).

FOCUS SCHOOL:
VAZARIN for protective sling when recasting Mesmer Skin.

If you want to use this build with my other build Mind Control Puppet Master Revenant Prime you would need to use an umbral forma at [Umbral Intensify] slot and add a Naramon symbol (dash) to where [Streamline] is.

Enjoy!
