Spellpack and SCS AI Options

[DavidW]

I'm in the process of revising the AI in the original Sword Coast Stratagems, and I've probably got time to make some modest allowance for the possibility of Spellpack being installed. It would be helpful to know:

(i) some foolproof way of detecting if Spellpack is installed;
(ii) your advice on how clerics, druids and mages optimised for the old spellset ought to be rethinking their strategy and spell choices if Spellpack is installed (L1-5 spells only).

If this turns out to be viable, I'll extend it to SCSII in the fullness of time.

Okay, this is starting to look pretty complicated. How well does the vanilla-game AI handle it, incidentally?

I take it the area of effect of Flame Strike isn't party-friendly. So probably that makes it hard for AI to use without the risk of incinerating one's allies. Is Color Spray area-of-effect or single-target?
