There are a lot of supplements for
Curse of Strahd, on the DM's Guild and elsewhere. For anyone who's interested, here is a partial list of the ones I am using and/or have read and considered. For this first list, I'm going to stick with more mechanical supplements, rather than story-based ones.
3,154,343 Eastern European Names (Free!)

I like to have this handy in case a random NPC needs a name on the fly.
Curse of Strahd Quest XP (Free!)
[FLOAT_RIGHT]
www.enworld.org
A resource from this very site! My group is mixed-level, and we're handing out XP every session, the old-fashioned way. I really wasn't sure how much to give for various story beats, so this guide was a godsend. I don't use every single item, but at minimum I always give them the quest XP for completing major story beats.
Darker Gifts: Curse of Strahd Expansion (PWYW)
-

My group doesn't have a lot of deaths, but even so, I wanted to make sure that the possible Dark Gifts were all interesting. I made my own custom list using the ones provided by WotC plus my favorites of what was in this supplement.
Gothic Inspired Agitations (Free!)
Gothic Inspired Agitations - A list of 50 random, weird, and spooky agitations for you to inflict on your players. Along with rules for use. Appropri

I'd love to use this one more than I do. It's a list of random spooky details you can toss into any scene to heighten the creepy atmosphere; some have mechanical implications, and some are just for flavor. I've basically given up trying to get my players to go along with a horror mood (they're just there to crack jokes and enjoy the gothy atmosphere), but for a different table, these could be great for scene-setting.
Monster Loot: Curse of Strahd
Monster Loot – Curse of Strahd - I want to loot Strahd von Zarovich! When brave adventurers face the dangers of the world, they want something to show fo

This one has been super-handy. My players have griped in the past about how 5E monsters never seem to drop loot. This gives me some minor but interesting things that I can list off when they sigh, "I don't suppose that guy had anything on him?"
Shops of Barovia (Free--GM Binder; looks best on Chrome)

Likewise, my group still hasn't shed their 3E expectations about regularly getting better gear. This supplement offered them something to spend their money on. I didn't use everything in it--just the things that seemed to have drawbacks equal to their benefits, because very little in Barovia should come without a price. Last session, the rogue finally rolled a one, and her Quiver of Venom exploded into a swarm of poisonous snakes at the worst possible moment. Dragomir's Grab Bag was a big hit with my party too!
