I'm pretty sure empowered spells were introduced in Act 1(when the Elites decide to start training you). Not the point though, I forgot to mention some other(minor) stuff.
First off, both acts could use some proof-reading(there is some preposition misuse here and there, and some words are clearly supposed to be different). Also, dark elves get a bit too dark at times, especially their queen. I could discern her eyes somewhat clearly in the throne room, but the only way to do it in the latter scenes(like bedroom) was her makeup. I hope you'll find a way to saturate them a bit more without breaking the 'dark' theme.
