๐Ÿ‰ Dragon-Forged Core Guide

Dragon-Forged Core is a Light-element Material forged at the Dragon Forge (mine level 90). It has two irreplaceable endgame uses: the core material of the Engagement Ring (required to propose), and one of the four offerings needed to Break the Final Seal (which clears the mine storyline and unlocks Seridia). It is also one of Seridia's Loved gifts and is used in some Woodcrafting recipes and Quests.

Complete Forge Recipe

Forged at the Dragon Forge. Takes 50 minutes, requires Blacksmithing Lv30, sells for 1,020t. Unlocked by completing the story quest "The Dragonsworn Tablet".

Monster Coreร—5Defeat Enchanterns in the mines.
Mistril Ingotร—1Mine Mistril Ore in the Ancient Ruins floors 81โ€“99 + Forge.

๐Ÿ’ก Mistril Ingot, Pink Diamond, and Ancient Firefly all concentrate on floors 81โ€“99 (Ancient Ruins) โ€” farm that section once to gather all three together.

The Dragon Forge

The station where the entire Dragon-Forged series is forged.

AttributeDetail
LocationMine level 90 (lower-left room).
UnlockQuest-progression based, NOT a skill level (per the official wiki).
IgniteOnce you reach level 90, use the Dragon's Breath spell to ignite the Forge (costs 2 Mana). This also opens the upper-right secret room containing the Dragonsworn Tablet.
RangeThe Dragon-Forged series (Fang / Core / Horn / Powder).

๐Ÿ’ก Not all forging happens here: Dragon-Forged series materials are made at the Dragon Forge (level 90), but the Engagement Ring itself is crafted at a regular Forge / blacksmithing station.

Unlock Quest: The Dragonsworn Tablet

This is why the Dragon-Forged series is quest-gated rather than skill-gated โ€” Juniper (magic) and Eiland (history) are needed in-story to interpret the tablet.

Quest TypeStory Quest
RequirementReach 8 hearts with BOTH Juniper and Eiland, and view both of their 8-heart events โ€” then talk to Juniper to trigger it.
ResultUnlocks the Dragon-Forged recipes at the Dragon Forge.

Core Use 1 โ€” Engagement Ring (Propose)

The Engagement Ring is forged at a regular Forge (40 min, Blacksmithing Lv30). The recipe is delivered by Elsie once you reach 10 hearts with a marriage candidate.

Dragon-Forged Coreร—1
Diamondร—2
Mistril Ingotร—4
Gold Ingotร—4

๐Ÿ’ก Diamond comes from Diamond Nodes in the Lava Caves (floors 61โ€“79) or the Stone Refinery; Gold Ingot from Lava Caves gold ore + Forge.

Core Use 2 โ€” Breaking The Final Seal

The Dragon-Forged series has 4 pieces, all forged at the Dragon Forge and offered at the Dragonsworn Tablet to Break the Final Seal. Offering all 4 unlocks the final mine levels and triggers the reveal of the Priestess's true identity (Seridia). It is also a hard prerequisite for proposing to Caldarus โ€” without it the game tells you "the time is not yet right, Caldarus is still bound to the Deep Woods."

Dragon-Forged Full Series (4 Pieces)

Light-attribute pieces (Core/Powder) use Monster Core/Powder + Pink Diamond + a Light rare; Dark-attribute pieces (Fang/Horn) use Void-series materials + Written Root. All forged at the Dragon Forge (level 90), all require Blacksmithing Lv30 + 50 min.

Practical Tips

  • First raise Juniper and Eiland to 8 hearts โ€” this unlocks the Dragonsworn Tablet, which gates the Dragon Forge recipes.
  • Push the mines to level 90 โ€” ignite the Dragon Forge (bring the Dragon's Breath spell, 2 Mana).
  • Farm the Ancient Ruins (floors 81โ€“99) in one pass to gather Mistril Ore, Pink Diamond, and Ancient Firefly together.
  • Defeat Enchanterns to stockpile 5 Monster Cores.
  • Forge the Dragon-Forged Core (50 min) โ€” it serves both the Engagement Ring and the Final Seal offering.
  • Complete Breaking the Final Seal to unlock proposing to Caldarus and Seridia's true-identity storyline.
  • Do NOT gift Dragon-Forged items โ€” the materials are precious; even though Seridia Loves them, the cost far outweighs the gift value.
