What's the difference between Prime Magic and Arcane Exaltation?

Question

I'm looking at both of these prime spells, and they seem to do almost the same thing. The first claims to award 3 magic power to the hero, while the second claims to award 2 magic power permanently.

What does it mean by that? Is Prime Magic not permanent, thus having to be cast (or something)?

Answer 1

IIRC,

Prime Magic only awards the bonus to spells in the Prime spell tree (e.g. Implosion)

Arcane Exaltation works for all trees. So if you're a primary Dark Magic user, you can pick up Arcane Exaltation to increase the bonus for your Dark Magic spells.
