Skill Points

Skill Points, or SP, is the measure of Luka's capacity to use Skills in a battle.

Each time Luka uses a skill, his Skill Points will drain according to the SP cost of the skill invoked. Without the necessary skill points, he is unable to utilize his skills.

The game begins with Luka possessing just 2 skill points. As the story progresses, his level increases, leading to an increase in the maximum amount of skill points that Luka possesses. The maximum amount of Skill Points that Luka can acquire hitherto is 10.

In some battles, Luka may start with very few SP, usually down to 1 or 0. As Alice states, this is due to the enemy catching and engaging him off guard.
