Grendel — Bile Shot
Optimised build. Regurgitate a guts victim as a toxic projectile. Nearby armor dissolves. Gastro leaves a bile puddle. Nourish still stays.

First Course first
This loadout sits at Optimised. It wants Forma, Helminth, or shards you may not have. Play the Starter until those systems are open — then this page is the upgrade, not the homework.
Open First CourseWhy this build?
Optimised for Grineer Steel Path, Demolysts, people who want Grendel to spit strip
Health: Not yet — Helminth, Steel Path, or Archon Hunts still closed. Play the Starter.
- Regurgitate is the strip button people forget exists. Strength is a breakpoint, then guns finish.
- You still keep Nourish. Viral plus strip is how Steel Path Grineer die.
- Empty guts = empty 4. Feast is the mag.
Don’t use this for: Star Chart only · new accounts · players without Helminth · ability-nuke as the damage
Helminth, shards, and a finished configuration
You don’t need the shards to run the loop. They are a later ceiling, not a gate.
Bring: Guns after strip — Once bile has peeled them, anything kills. Viral from Nourish is already on the shot.
Alternative if…
- Star Chart only → First Course
- This is too much Forma / cost → Meatball — Steel Path

Did this still work for you?
Your note, in this browser. Separate from Codex verification — the stamp on the card is editorial, this is yours.
Readiness

- Required mods 0/9 · required — 0/9 named
- Forma 0/4 · required — 4 on the card. Codex does not track installed Forma.
- Helminth · optional — Not required

Investment: 4 Forma · Reactor · 2 shards · 3 specialised mods. Typical farm ~4–6 hours. Trade if a route is vaulted.
Codex Checked · Compared against current game data for this update. · Update 43.5 · 5 Sept 2026 · PC · Current
Medium confidence. A solid recommendation with more situational dependencies. Confidence is not verification. Verification is separate: Codex Checked against Update 43.5.
Your next step
Next: Meatball — Endgame
Unlock Helminth, Steel Path, or Archon Hunts before this upgrade is honest.
