Like the titles says. I'm asking about how it works is it discounted for one skill or all the skills listed. I know it's honestly all down to how the GM wants to balance it. Yet I want to get a rough idea since I been. Playing around with a few more adapt builds I want to post and want to make sure I got the concept right or not.

I'm guessing you meant "power" not skills. The Adept Ways give a discount on 1 adept power for every 2 points of the adept's Magic Rating. The rules are at the start of the Adept Qualities (page 176).

PS: It's AdEpt with an "e" the word adapt (with an "a") is a verb.
