I don't age anyway...

I cast Switch Location on Psyblade, then watch him go through the tortures he intended for me.

I would place DB in an adamant room with a permanent anti-magic field active in it, bar the doors (all adamant, of course) and let him spend the rest of eternity in a locked room with no magic. Food and water is provided via a small slot high up on a wall, from which the sustainance drops to a receptacle (made of adamant, and bolted down by adamant bolts). Note that this procedure is carried out by mechanical servators, each carrying anti-magic artefacts, to prevent any clever spells being cast before DB is locked up.

Now that's evil.

Thaumaturge...your strategy is quite clever, but Silver Fire can break through antimagic zones. Praise be to Mystra!

I would do the same thing to Thaumaturge, and see how HE manages to get out!

I will find the Necronomicon, De vermiis mysteriis, and the lost city of Ry'leh and raise an army of elder gods, demons, and undead to conquor and consume the world. And to my mortal minions I offer the option of being eaten first.

First, I hire some mercenaries to kidnap JADguy.
Then, I strap him to the rack.
Then, I stick tiny pins in him all over his flesh, then enchant them to get hotter or colder (depending on the needle) as the rack loosens, and more temperate as it tightens.
Then, I'll enchant the rack so it gradually cycles between almost unbearably tight and just inescapably loose.
