Following the March 10th Fields of Mistria update, the Fire Seal is finally accessible after completing the preceding altars. Unlocking it requires four offerings: a Faceted Rock Gem, Rockroot, Emerald, and a Sealing Scroll. Let's explore how to obtain each item.
Obtaining the Fire Seal Offerings in Fields of Mistria
Finding the Faceted Rock Gem

This rare artifact is located within the Fields of Mistria mines, specifically on floors 50-59. We discovered one on floor 56 after some digging. Use your pickaxe or shovel to unearth it from marked ground areas. Be prepared for some grinding; it's a relatively uncommon find.
Locating Rockroot

Rockroot is a common forageable plant found on floors 50-59 of the mines. If you frequently explore these levels, you might already have it. Look for a dark, root-like plant (pictured above). Only one is needed.
Acquiring an Emerald

Emeralds are the easiest offering to obtain. They're found in geodes throughout floors 50-59 of the mines and are relatively common. You can also find them by breaking large boulders in Mistria, purchase them cheaply (200 tesserae) from Balor's Wagon, or craft them using the Stone Refinery (unlocked via the March 2025 update).
Obtaining the Sealing Scroll

The Sealing Scroll is obtained through a quest triggered by speaking with Juniper after discovering the Fire Seal. This involves commissioning Balor to acquire the scroll, requiring the following payment:
- 10 Silver Ingots
- 10 Rubies
- 10 Sapphires
- 10 Emeralds
These materials are readily available in the mines if you haven't already collected them. Deposit the payment in the bin near Balor's Wagon.
Unlocking the Fire Seal
Once you've gathered the Sealing Scroll, Faceted Rock Gem, Emerald, and Rockroot, return to floor 60 of the mines and make your offering. This will unlock the Fire Seal, revealing a new biome and further content within Early Access.
