Draco Temple - Blox Fruits (Draco race)

The Draco Temple (or Draco Room) is the training room dedicated to the Awakening of the Draco race. It is hidden behind the Dojo Vault of the Dragon Dojo, on Hydra Island, in the Third Sea. Entering it requires extensive preparation: two fully leveled weapons, the Leviathan Heart, the frozen island, and all lanterns lit.

How to get it

At the Dragon Dojo on Hydra Island (Third Sea). The entrance is the Dojo Vault, right next to Uzoth.

Opening the vault, step by step

Craft the Dragonheart and Dragonstorm from the Dragon Hunter.
Level both weapons to 500 Mastery each: this is what lights up the yellow and green lanterns.
Get the Leviathan Heart with the help of the Beast Hunter, bring it to Hydra Island, and sail your boat through the waterfall. The island will then begin to freeze.
Once the island is frozen, talk to the Dragon Wizard, then go light all the lanterns to open the vault.

What awaits you inside

On your very first entry, you enter a room where a nameless NPC awaits you, displayed as "???". Interacting with them triggers a cutscene: a hologram of the Prehistoric Island appears, then the NPC says "Your journey is near the end. You must complete the final trial."

Then complete the Trial of Flames at Prehistoric Island. Two dialogue options then open up with the NPC:

Archive: replay the cutscene and dialogue.
Training: allows you to buy gears corresponding to the training you have sufficiently leveled. Details about these trainings can be found with the Ancient One.

Common pitfalls to know

The hologram room closes if you haven't made your upgrade before completing the next Prehistoric Island. Don't put off the purchase.
If you don't have the Draco race equipped, or if you don't yet have access to the room, the NPC displays no option and simply responds "...". This is not a bug.
The room arrived with Update 24.
Don't confuse it with the other temples in the game: this page only covers the Awakening of the Draco race.
