To get Stage 2 Haki in Blox Fruits, first, buy Aura from the Ability Teacher in the First Sea for $25,000. Once you have Aura, you need to level it up. Activate Aura and then take hits and deal damage to gain Aura experience points (XP).
You can use guns, swords, melee weapons, or different fighting styles to level up Aura faster. This helps in gaining XP quickly. As you keep using Aura, it will gradually level up to Stage 2.
After leveling up your Aura to Stage 2, visit the Aura Editor NPC. This character will help you change the active stage of your Aura. By following these steps, you can progress through the stages of Haki in the game.
Reaching Stage 2 Haki in Blox Fruits is a rewarding process. It allows you to unlock the full body effect eventually. Make sure to use various weapons and styles to speed up the leveling process and enjoy your enhanced abilities in the game.
