Warframe · Grendel Prime

Eat the tile. Keep Nourish. Everything else is seasoning.

A walking stomach in armor. Grendel vacuums enemies into his gut, buffs the squad with Viral and energy, then bowls, slams, or spits them back as bile. Nourish is the best Helminth in the game — which is why it stays on him.

Heal, Viral on attacks, energy multiplier. Squad-wide. Do not Helminth this.

Pulverize

Become a ball. Roll, knock down, jump-slam. Heals as you go. Catapult launches.

Regurgitate

Spit a guts victim as a toxic projectile. Splash slows and strips armor. Gastro leaves a puddle.

First Course

Learn the frame.

Best for: Star Chart, first Grendel, learning guts

Feast a pack. Nourish. You are now Viral, healing, and printing energy. Do not vomit yet. Do not subsume Nourish. Ever.

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.

First serious version.

Best for: Junctions through the Outer Terminus. Steel Path is the next card, not this one.

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.

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.

Meatball — Steel Path

Your first endgame-capable version.

Best for: Steel Path Star Chart, Circuit, first Archon. Helminth is the next card.

Nourish up, Feast a crowd, Pulverize. You are a Viral bowling ball that heals while it rolls. Catapult if you want to fly. This is the peak you can run the day Steel Path unlocks — galvanized / arcanes, no Helminth.

Pulverize is Grendel's joke that still clears Steel Path when Nourish is up and the gut is full.

Best for: Incarnons, melee, squad energy, people who picked Grendel for 2

Roar or Eclipse over Pulverize. Nourish stays. You are the best Viral / energy battery in the game, on purpose, with guns.

This is the config that exists because Nourish is the best buff in the game. You do not subsume it off Grendel to put it on someone else — you play Grendel.

Regurgitate a guts victim as a toxic projectile. Nearby armor dissolves. Gastro leaves a bile puddle. Nourish still stays.

Regurgitate is the strip button people forget exists. Strength is a breakpoint, then guns finish.

Key mistakes

Helminthing Nourish
You just deleted the reason people play him and the reason people steal him. Put Roar on 3 instead.
Pulverize on an empty gut
Sad hamster. Swallow first.
Building shields
95 shields. You are a health and armor frame. Vitality, Adaptation, guts.
