As if the DLC practices of Arise weren't bad enough, did you know that the costumes come with additional titles and thus extra skills! Its true! Because nowhere on the internet seemed to list out what you get, I bit the bullet and dropped the $30(!!!) dollars to buy all the costumes with skills. Hopefully that will let you buy only the ones you really want, or be stronger willed than I and just ignore them entirely. 2021 AAA Publishing at its finest!

This guide will list the skills they provide as I unlock characters through the story.

For those who just can't get enough SP, you could spend your money outside of the game to buy more SP, or you can channel the dark arts to grant your desires. The following profane text may be helpful to such practitioners. Please note, that because Steam might not like people discussing such things, I will not explain how to use this, or what uses it exactly. I am also not responsible for damage to your saves, your game, your computer, or your soul caused by the improper or proper use of such wicked words. Standard MIT License applies. For those confused and intrigued by these things, may I suggest learning about reverse engineering, assembly, injections, auto-assemblers, and engines that provide tools to work with these things? (Protip: Use VEH when crafting your own wicked incantations.)
