Roblox has come out with another winner with the creation of Blox Fruits. This island-based exploration game has players jumping from location to location completing quests. Beating up monkeys, sky wizards, and others rewards both XP and weapon mastery. Fruits can be bought to upgrade hand-to-hand combat moves, and swords can be mastered to deliver devastating blows. Alongside the weapons, Haki’s can also be installed. Once you have yourself one, you need to know how to upgrade Haki in Blox Fruits to really get ahead.
How to find a Haki in Blox Fruits
There are two types of Haki you can get. The first is Observation Haki and the second is Enhancement Haki. They must be found or purchased from different areas on the map.

This allows you to evade incoming attacks whilst active. It can be found at the top of the Upper Skylands. You must be over level 300, have $750,000, and have killed Saber Expert. Once you have met all these criteria, you can speak to the Lord of Destruction and purchase the Observation Haki. Once you have purchased, you can start your upgrade of the Haki in Blox Fruits.
Enhancement Haki
This is the favorite Haki of most players. It enhances all your attacks and grants 1XP for every successfully landed attack. It requires only $250,000 but is tricky to find. You need to go to Frozen Village in the First Sea. On the perimeter of the island, there is an entryway to a secret cave. Talk to the Ability Teacher and buy the Enhancement Haki.
