Hmmm, can't find that clarification anywhere. Just people assuming that because it's not listed in the chargen area, it's not allowed.
And yeah, I realize it'd be the 6th Initiation. Considering you're a full-fledge Mage minus Astral Projection, that seems pretty balanced. if I were my GM, I think my house rule would have likely limited the magic ability (perhaps only sorcery or conjuring) and a choice of either starting out with the ability to buy Power Points, or some starting spells. I also don't "like" the House Rule, I just think it's fair. I admit, I took Adept over full Mage purely to get the 3.5PP Initiative boost. I have no interest in being a Mystic Adept and would just 'play' it like a superior Quickening of a spell.

Now I either have to wait 70 karma later for level 4 initiation, or quicken it 13+karmaboost karma later after I learn the spell. Comes out about the same in the long run, and as a Mystic Adept, I can consider conjuring at least... Anyhows, I'm afraid I've derailed this thread too much. I'll start a new thread if anyone wants to continue this run of discussion.
