So I'm trying out Chummer, and I can't seem to figure out where to awaken a character... I'm sure it's obvious, because it's not in the WIKI and I can't find anyone else asking it, but it is evading me...

Any help would be appreciated!

(Note< I have a new character made, Magic is ghosted so I can't improve it, and I can't find anywhere to define mag/adept)

You need to add one of the awakened qualities. On the first tab, on the left, there should be a large text area to list qualities (if you are human it would be empty, but other metatypes have their inate qualities listed). Click Add Quality, then find one of the Awakened Qualities (Adept, Mystic Adept, or Magician) and either double click, or click the add quality button (or if you want to add more qualities you can click Add & More.

This is the same for a Technomancer needing to add the Technomancer Quality to be able to have Resonance.
