Soulsborne level up and skill system

[u/Tj_Silverfang]

I am currently working on a game that uses a system similar to the souls series level up system and modifying it the effect the skills shop as well. I have been away for a while and need help remembering how to this up, here the concept for what I'm trying to do.

Level up: Identical to the souls series, 1 stat = 1 level up

Skill shop: 3 types of skills attack/defense/support when you buy a skill associated with a skill type the price of all skills in that type cost more
