Baddest DnD Artifact (Evil)

Would it be the Bloodstone?

Hand of Vecna?

Stormbringer? I know Stormbringer is not exactly DnD, but I have had some DM's bring it into their campaigns.

Jez I haven't even opened a D&D book for 15? years but I still recall that Hand of Vecna... nasty stuff!

For some reason it reminds me of the Tomb of Horrors module.

the dragon orbs are nasty...

Crenshinibon from the Icewinddale Trilogy ?

The Dragon Orbs can make a formidable army of breath weapon death.

Think of the possibilities?

The Sword of Kas was the first thing that came to mind.

I'll have to check out the 1st e DMG to look at the oldies..
