Way of the Kensei (5A)

Starfox's 5th Edition Fan Page

Path of the Kensei Kensei's Shot You add a martial arts die to the damage (instead of a d4).

Sharpen the Blade At 11th level, you gain the ability to augment your weapons further with your ki. As a bonus action, you can expend up to 3 ki points to grant one kensei weapon you touch a bonus to attack and damage rolls when you attack with it. The bonus equals the number of ki points you spent. This bonus lasts for 1 minute or until you use this feature again.

The attack bonus does not stack with any attack bonus (due to a magic weapon, spell, et al) the weapon already has, only use the best bonus.
