Ninja Skills are purchasable character upgrades in Ninja Gaiden 3: Razor's Edge. Press Select to access the Ninja Skills screen, then choose which upgrades you want to learn to power up your character. By meeting certain conditions, the number of upgrades you can select will increase. Colored hexagons indicate ones you have already learned, while the darkened ones indicate that you do not have enough Karma to learn them.
Karma is earned by killing enemies and other in-game actions. It can be used to upgrade weapons, Ninpo, maximum health, and more. It also allows access to more moves. Character upgrades only apply to the character currently being played.
Each upgrade displays the total number of Karma you currently have, the amount of Karma you need to learn it, and the total amount of Karma you have collected. The Ninja Skills screen also displays the number of Crystal Skulls and Golden Scarabs you have discovered.
