How To Unlock the Deep Woods in Fields of Mistria

To unlock the Deep Woods area in Fields of Mistria, you must break the Fire Seal and use the new Dragon’s Breath spell to clear the obstructing vines. Begin by collecting four items to place on the Priestess’ Fire Seal altar located on Floor 60 in the mines: a Faceted Rock Gem, a Rockroot, an Emerald, and a Sealing Scroll. You can find the first three items between floors 50 and 59. To obtain the Sealing Scroll, you'll need to collaborate with Juniper and Balor.
To help Balor acquire the Sealing Scroll, deposit the following items in the bin by his wagon:
- x10 Silver Ingots
- x10 Rubies
- x10 Sapphires
- x10 Emeralds
After fulfilling these requirements, speak with Balor again, and he will inform you that the scroll will be available the next day. Once you have the scroll, you can complete the offering at the altar.
Breaking magic seals usually concludes with a message from the mysterious mines Priestess, unlocking a new biome. However, this time, the plan goes awry, and the Priestess urges you to leave before the Sealing Scroll traps you inside. As your health diminishes, Caldarus appears in his human form to rescue you, then retreats to his temple in the Deep Woods to regain his strength.
Caldarus leaves you with the Dragon’s Breath spell, which you can use to burn through the vines blocking the entrance to the Deep Woods. This spell also helps uncover other previously inaccessible areas on the map. To use it, equip Dragon’s Breath from the pause menu and activate it in front of the entrance to permanently unlock the Deep Woods and other areas.

How To Find Caldarus

After breaking the Fire Seal, you can locate Caldarus within his temple in the Deep Woods. This area is north of the Eastern Road on your map, and accessing it requires the Dragon’s Breath spell. Caldarus’ exact location will be marked on your map like other NPCs, in the northeast corner of the area.
To reach him, enter the Deep Woods, turn right, and use your axe to remove the stump blocking your path. Continue north until you arrive at the temple, where Caldarus awaits inside.


Once the Deep Woods are unlocked, you can use the Dragon Statue on your farm to fast travel to this area and visit Caldarus for just 10 Essence, saving you time compared to traveling on foot or horseback.
You can also interact with Caldarus through his statue in spirit form.
