Blackfire Adept Rework PEACH

[NikolaTesla]

I'm running an IRL Wrath of the Righteous campaign and found the Blackfire Adept PrC to be flavorful but somewhat lacking in substance and power. So I decided to rework it a bit. Please let me know what you think and whether it seems balanced, or what modifications I should make to it.

It certainly looks and reads very cool. Unfortunately, I have basically nothing to input in terms of balance, as I mostly run games in settings without summoning. Reality burn looks awesome.
