To get the Dragon Breath in Blox Fruits, you need to reach level 700. This level grants you access to the area where Sabi, the NPC who teaches Dragon Breath, is located.
Next, collect 1500 fragments. These fragments are essential to purchase the Dragon Breath fighting style from Sabi. You can gather fragments by participating in raids and completing quests.
Once you have the required fragments, head to the Kingdom of Rose. Look for Sabi on the fifth mini arch on the wall on the left side when facing the cafe. Talk to him to learn the Dragon Breath fighting style.
By following these steps, you will be able to master the Dragon Breath fighting style in Blox Fruits. Enjoy your new skills and dominate your battles!
