Grendel — First Course
Star Chart build. Feast a pack. Nourish. You are now Viral, healing, and printing energy. Do not vomit yet. Do not subsume Nourish. Ever. Primed Continuity and Primed Flow are the first real upgrade — not Blind Rage.

Why this build?
Star Chart for Junctions through the Outer Terminus. Steel Path is the next card, not this one.
Health: Inventory unknown — Mark what you own. Until then this is a recommendation, not a test you failed.
- Nourish is the best Helminth in the game, which is why you keep it on Grendel. Feeding it to Helminth is how you make a worse Rhino.
- Feast is the engine. Empty guts mean Nourish is a weaker buff and the armor passive is asleep.
- You are a health tank. Shields are a joke. Vitality is not optional.
Don’t use this for: Steel Path endurance · level-cap content · solo level-cap
Accessible mods and a working energy / survivability loop
Bring: Any gun — Nourish puts Viral on it. A decent primary is enough. The ball is later.

What is actually up
30 minutes, one hour, or two — matched to this loadout, not a dump of the Origin System.
30 minutes
Farm Steel Charge
One named gap. Invasion / Nightwave
60 minutes
Steel Charge, then Forma
Finish the missing named card, then spend a Forma if a polarity is still fighting you.
120 minutes
Two farm routes, then a test run
If you are logging off after this, stop at the named component. Do not start a second Forma session tired.

Who this is for
Play this build from zero
You survived the locator missions (or bought him) and the gut meter is new.
- Time to a playable copy
- Same day. Intensify, Stretch, Continuity, Vitality.
- First mission to practice in
- A low Infested Exterminate. You want clumps to swallow, not a sniper hallway.

Pocket card. Stick this on a second screen; the long version is the mission below.
- 1Walk into a pack. Feast (1). They vanish into the gut. You got armor.
- 2Nourish (2). Health regen, Viral on your attacks, energy orbs and energy sources hit harder. The squad gets it too.
- 3Shoot. Viral is on the gun. Energy is not a problem.
- 4Pulverize (3) and Regurgitate (4) wait until you mean them. Starter lives on 1 and 2.

Shoot. Recast 2 before it dies
That is the whole starter. Ball comes later.
Common mistakes
Feasting a Nullifier from the front
The bubble still exists. Shoot it, then eat.
When this feels easy
- 1Do not subsume 2Not now, not at endgame. Next configs all keep it.
