What to know
- Minnak the Cat is tied to a secret NPC that only appears after Goblin Lord quests
- The NPC is hidden behind a false wall inside the Goblin Lord’s cave
- Minnak is found inside a small hut in Frostspire Expanse town
- Returning the cat rewards you with Grassite, a secret common ore
Minnak the Cat is a small but important quest item in The Forge. This hidden interaction rewards careful exploration rather than combat, and it also unlocks Grassite, a secret ore used in niche crafting and rare sword variants.
If you’re progressing through Frostspire Expanse and want to uncover everything the game hides off the main path, this guide walks you through every step clearly.
Location of the Hidden NPC
After completing the Goblon Lord's quests, you need to find a hidden passage behind him.

Jump on the coin-like blocks and get to the spot near the leaves on the wall behind the Goblin Lord. Inside the hidden area, there is a prisoner named LocalModuled. This is your secret NPC.

He tells you about his cat, Minnak, and asks you to get it for him.

Where to find Minnak in the Forge
Now that you know about Minnak from the hidden NPC, LocalModuled. Your next task is to find the cat. Keep in mind that the cat is not available or seen anywhere, as the NPC suggests. You need to look around the town.
Exact location of Minnak - Inside a hut in the Frostspire Expanse.
This hut is located behind Bjorn's Hut in the town. You need to hop over his hut and find the one through which you can pass the wall.

Find Minnak and press E to stash it in your inventory.

Once you have successfully retrieved Minnak, you can see it in your stash.

How to get the secret ore in the Forge
Go back to the hidden NPC in the Goblin Lord's cave, return the Minnak to him.

As he promised earlier, he gifts you the ore, Grassite.

Prerequisites before Minnak can appear
Before Minnak the Cat can be collected, your save must meet a few hidden conditions. The most important requirement is completing all Goblin Lord–related quests, which unlocks access to the false wall area behind him. If even one quest step is unfinished, the hidden passage will not be interactable, and LocalModuled will not spawn.
You also need full access to Frostspire Expanse town. While Minnak itself does not require combat or level checks, reaching the town area reliably usually means you’re already progressing through Island 3. If the hut behind Bjorn’s Hut is inaccessible or blocked, it’s a sign that your world state hasn’t fully updated yet.
Grassite crafting overview
Grassite is mainly used to enable Grass-aligned weapon variants:
- Works in Colossal Sword forging
- Enables a chance to roll Grass Excalibur when included in the recipe
- Confirmed by community testing during Frostspire-era updates
