This is the 1st Helminth Revenant build.
Build B: https://overframe.gg/build/113533/
Build C: https://overframe.gg/build/113534/
This build is mainly focused around Reave and Larva, but the other two abilities are also very important to the playstyle.
Its a pretty simple concept, group them together and smash right through them. For most high level enemies this will drain around 75% of their health, for Enthralled enemies this will one shot them.
It is also important to keep Mesmer skin up, it makes [Revenant] invincible. This is made easier because when you are Reaving your Thralls they will restore your Mesmer stacks.
Very satisfying, lots of fun.
