VERY IMPORTANT NOTE: [Grendel]'s Nourish heal and pulverize damage scales off enemy levels, but doesn't scale anywhere near as quickly as enemy health does. You'll eventually have to resort to Feast cancelling and Nourish heals to do serious damage.

Replace the blank slot with [Gourmand] for the actual build. This build utilizes [Grendel]'s interaction with Gloom to restore health infinitely while in Pulverize. [Umbral Fiber] is slotted here in favor of [Adaptation] due to [Adaptation] not maintaining uptime during Pulverize.

PSF is not needed on this build since we can get full resistance to all effects, including self-stagger, by utilizing his [Hearty Nourishment] augment. While this does [Sacrifice] potential range, it makes [Grendel] immune to Slash and Toxin, which are just about the only things that can stop this build from functioning. With a relatively low drain, and 2.3 seconds immunity per enemy, it should only take 13 enemies in [Grendel]'s stomach to keep up with his ~30 second Nourish duration.

Additionally, Gloom does not count the enemies in [Grendel]'s stomach for energy drain as they cannot be slowed. Gloom is also not disabled on casting Pulverize. This is the crux of the build. Activating Gloom, consuming as many enemies as possible, and jumping around while in Pulverize will fully heal you at high levels, effectively allowing for infinite Feast energy. This is because Gloom scales off damage dealt, so the healing consequently scales off the number of enemies in your stomach. In a pinch, you can also use Nourish to boost your damage, armor, and energy, as well as grant up to 92 seconds of full status immunity. Your teammates can even gain these benefits from the meatball of gore flying across the map. Delicious!
