Enhancement would suck, and sacred/profane/whatever wouldn't make sense. I could call them class bonuses, but inherent is there to indicate they are a permanent part of the Ascendant as a result of his heritage manifesting itself.
If you still don't understand how the spell-like abilities work, I'm not sure I can help you.
I see you aren't familiar with my design philosophy. Classes should not have to pull out cheese to be able to be in the same party as a wizard and not cry themselves to sleep. Does this mean making tier 1 classes? No. Does it mean making high tier 3 classes that have more options than "I power attack for full"? Better believe it.And It's not terrible brokenness, thats just it. It's not min-max. Which is usually what break things. It's max-min, with the min at a point what you would otherwise have to min-max for.
