Recommendations for Curse of Strahd if ONE "supplement" is allowed per character?

[saintstardust]

So the idea is that one supplement (EE, SCAG) or UA article is allowed per character created to arrive in Barovia. What looks interesting? From a previous thread, the Modern Magic looks limited without electronics. Mystic v.2 has potential but the level 10 feature is a killer. Eberron Artificer maybe?

I mean, I know Modern Magic stuff would be more limited without electronics being abundant in the world itself, but I personally would still go for it, solely for the Find Vehicle spell. What could be more fun than cruising around Bariovia in my fiendish SUV?

Hmm, the summoned vehicle should count as electronics perhaps?
