[Catapult] allows [Grendel] to traverse areas with Pulverize very quickly. We utilize a subsumed movement ability to either increase our speed outside of Pulverize while we're using Feast on enemies or to give us some QoL.

Fire Walker is chosen because it gives use additional movement speed and status immunity. Infested Mobility and Molt also work but they really aren't needed while you're in Pulverize due to the way it handles movement speed.

[Brief Respite] allows [Grendel] to get a significant portion of his shields back, making his shield gates last longer. You can abuse this even further by running a Decaying Dragon Key.

Survivability isn't a big focus on the build because you don't have the ability to defend yourself while you're zooming around in Pulverize. None of these mods are necessary in most content due to how bad the enemy AI is at targeting [Grendel] while he's in Pulverize.

Range is low but we have to keep it just a bit above the minimum or we won't have the range to eat any enemies with Feast.

[Natural Talent] helps your abilities to feel more fluid. It synergizes with several aspects of the kit including [Brief Respite] and Nourish spam.

Arcane [Guardian] is a flex arcane that increases your survivability in general content. It can be replaced with any other arcane to suit your playstyle.
