Yes, you can romance Caldarus in Fields of Mistria — the dragon who helps you out around town was teased as a romanceable candidate from launch, and the 1.3 update finally lets you unlock his romanceable human form. The route begins on floor 60 of the mines, where interacting with a tablet starts the "Breaking the Fire Seal" quest chain that ends with Caldarus taking human form and settling in The Deep Woods. Once unlocked, you can visit him at his home, give him gifts, and invite him to the Shooting Star Festival. Full dating and dedicated heart events have not shipped yet, so for now his bond grows mainly through story progress.

Can You Romance Caldarus?

Caldarus is a confirmed romance candidate, and the 1.3 update turns the long-running tease into actual playable content. Unlocking his human form makes him a villager you can visit and give gifts to, which is the foundation of his romance route. According to Polygon's guide, players jumping into the update on an existing save with most older content finished should not have to worry about playing much catch-up. Community reports on Reddit add that the devs appear to be deliberately holding off on deeper romantic content while the game is still in Early Access, so expect the route to expand in future updates.

How to Unlock Caldarus' Human Form Step by Step

The quest itself is fairly self-explanatory, with NPCs like Juniper and Balor walking you through each stage of the process. You may notice quests from Adeline and the others coming in after the update, but you do not have to pay attention to them, as they are not required for unlocking Caldarus. If you want to expedite things, gather the materials listed further below in advance and follow these steps:

  1. Reach the 60th floor of the mines and interact with the tablet to start the "Breaking the Fire Seal" questline.
  2. Talk to Juniper to begin deciphering the tablet, then follow the quest line with Balor — you will need to wait a few in-game days for him to find what you need.
  3. Provide Balor with 10 sapphires, 10 rubies, 10 emeralds, and 10 iron ingots to receive the sealing scroll.
  4. Give the fire shrine its four required materials: one emerald, one rockroot, one faceted rock gem, and the sealing scroll.
  5. After the cutscene, head to The Eastern Road and make sure you have your axe with you.
  6. Use the Dragon's Breath spell on the vines blocking the area in the northeast, as instructed during the cutscene.
  7. Head through the newly opened area to access The Deep Woods.
  8. From the entrance of The Deep Woods, head right and chop the tree stump blocking the way — this requires at least a copper axe.
  9. Follow the path to Caldarus' home and talk to him inside.

Fire Seal Quest Materials Checklist

Gathering everything before you start saves you several in-game days of back-and-forth, especially the waiting period while Balor researches the tablet. The gems and ingots are the biggest ask, so plan a few mining runs ahead of time. Here is the complete checklist:

  • For Balor, to obtain the sealing scroll: 10 sapphires, 10 rubies, 10 emeralds, and 10 iron ingots
  • For the fire shrine: one emerald, one rockroot, one faceted rock gem, and the sealing scroll
  • Tools: your axe, upgraded to at least copper, for the tree stump in The Deep Woods
  • Spells: the Dragon's Breath spell, for burning away the vines on The Eastern Road

Caldarus Heart Levels Explained

In Polygon's playthrough, Caldarus was immediately at a six-heart relationship after the unlock, but your mileage may vary. The official patch notes for the 1.3 update state that his heart levels "will now increase as intended with key story points," meaning you may have fewer hearts with him depending on your story progress. This makes his affection system unusual among the villagers, because it is tied to main-story progression rather than purely to gifts and conversation.

Community players add useful context to this. Many believe his hearts are connected to the seals in the mines, at roughly two hearts per seal broken 待确认. Redditors also point out that the seal-breaking questline and the human-form unlock sequence essentially serve as his six-heart event, since he and the farmer are already trusted friends by the time he moves into The Deep Woods rather than complete strangers.

Story Spoilers: Why Caldarus Stays Home

Spoiler warning: this section discusses story beats from the Caldarus unlock in the 1.3 update.

The game explains directly why Caldarus keeps to himself after gaining his new form. Saving you and taking human form took a lot out of him, and he needs time to recover — community players describe him as being in a chronically ill, low-energy state, a portrayal that chronically ill fans say they found genuinely relatable. He also does not want to frighten the other villagers, so he is working out how to acclimate to the town once he is feeling better. A popular community theory holds that he will start exploring Mistria and its festivals once his power returns enough to hide or mask his more dragon-like features 待确认.

Visiting Caldarus in The Deep Woods

After the questline, you can use the Caldarus statue on your farm to teleport straight to his domain in exchange for 10 essence, which makes daily visits cheap and convenient. Community reports describe his new home life in warm detail: he keeps a mini farm, studies scrolls left behind by the Dragon Priestess to update himself, and has taken up playing an instrument. If you visit him often, he will tell you about his indirect encounters with the villagers — guiding Juniper out of the woods, watching Hayden and Olric visit their family members' graves, and requesting coffee beans from Balor anonymously. These small stories are currently the main way to get to know him as a person beyond the "all powerful dragon" exterior.

Inviting Caldarus to the Shooting Star Festival

Caldarus becomes an eligible invitable NPC for the Shooting Star Festival, as long as you have his human form unlocked, giving you an early festival evening with the dragon. Community players have also reported that he has new interactions related to the summer festival added in a recent patch. Festival invites are among the few explicitly romance-flavored activities available with him right now, so do not skip them. For what it is worth, many players say that between March, Balor, and Caldarus, the dragon would be their easy first pick if he simply had more content.

What Comes Next for the Caldarus Romance

The biggest gap in the route, according to community reports, is the absence of traditional heart events — Caldarus is the only candidate whose bonding happens through the main story instead of dedicated scenes. Reddit players speculate that dating will begin around eight hearts once the full romance system is implemented 待确认, and many hope a future update gives him his own event or quest line that makes him a proper member of the town. The devs have been trickling content out in small-to-medium chunks during Early Access while ironing out bugs, and players widely expect a larger flood of content at full release. Until then, breaking the seals, gifting, and festival invites are the whole of the Caldarus romance.
