Haki Master

Those who wish to rise to the top without a devil fruit, a task that might seem impossible and hard to many but once one archives the power they will soon learn that Haki reigns supreme.

• Increase one ability score of your choice by 1 to a maximum of 20. 
• You gain four Haki techniques of your choice, and you can use further Ability Score Improvements to gain an additional two Haki techniques, if you meet the required level. 
• You gain a number of Haki Points equal to your Proficiency Bonus and regain uses on a short rest. You regain 1 expended haki point each time you roll a 20 on the d20 roll for a weapon attack or unarmed strike, or deal a killing blow to a creature of significant threat (DM's discretion).
