I'm a sorcerer, and I feel silly even asking this question, given the following:
1) I've been playing since early release.
2) I'm currently VR6.
3) My Daedric Summoning is at level 50.
What I can't figure out it this: How does a sorcerer gain the ability to summon a clanfear? I have the volatile familiar, and I have the twilight matriarch. The clanfear isn't even an option in my skill list, yet I see lowbie sorcerers running around with clanfears. What am I overlooking?
