I have a power gamer group and want to keep Curse of Strahd scary, what magic items would you give to Strahd himself?

Why give him magic items that can be stolen or looted when you can give him powers that even the field in scary ways:

From the Conclave Dryad:

Suppress Magic (Recharge 5–6). The dryad targets one magic item it can see within 120 feet of it. If the magic item isn’t an artifact, its magical properties are suppressed for 10 minutes, until the dryad is incapacitated or dies, or until the dryad uses a bonus action to end the effect.

now ive never read the thing, isnt the point that you CANT kill every monster? strad will just come back anyway IF they manage to kill him

as for keeping it scary, I said before and I'll say it again! strad can control minor things across barovia. he can make his face paper in the clouds, the wind whisper his name. the land was made for him, and the PCs are not welcome

I actually like the idea of having given the party an opportunity to steal things that otherwise life will be made hard for them

 Oh totally for the campaign, but for the final fight I don’t want it to be over basically before it began
