Who are good people to pickpocket?

Sloty

Since I have a bard, I am wondering who are some good targets for pickpocketing?
I know Arundel is one are there some other good ones?

Beetle

Oswald Fiddlebender has some nice items, iirc

Merina

Orrick ... two items

Thanks to @Haeravon :

Amulet of Metaspell Influence

You can steal this amulet from Orrick (AR2102).

Amulet of Protection +1

Ring of Free Action
Lonelywood [HEART OF WINTER]
You can steal several of these rings from Purvis (AR9110) over
the course of the Heart of winter expansion-every time he buries
another body, he'll have another one of these rings. That's
three, in total, that you can steal.

Ring of Free Action
Castle Maluradek [TRIALS OF THE LUREMASTER]
You can steal this ring from Harald, who is in the northwestern
tower (x=9704).

Ring of Greater Resistance

Also, @Abel here (http://forums.beamdog.com/discussion/36401/pickpocket-list) mentioned that some creatures possess items that cannot be stolen but can be retrieved on their corpse. For example, Hjollder has a Warhammer +3 Defender (best of its kind in the game).

This was true for the original game but it's not longer the case in IWD:EE.

Purvis now only has one Ring of Free Action, regardless of when and how many times you pickpocket him.

It's worthwhile to try to PP any named NPC, in general.

Also note that Oswald's Necklace of Missiles is no longer useless, as you get 8 missiles (fireballs) now instead of 1. At non-HoF difficulty levels, 8 fireballs are rather handy in the early game, as you can get the Necklace before even fully finishing Kuldahar Pass.

Huh. Wish I had known that before my dwarfs went through Dragon's Eye. Those beetles are really annoying what with the way they spit acid. Rather than slowly sling/arrow/bolt my way through that narrow tunnel to get the axe, it'd have been useful to be able to fireball the lot of them.

Agreed. The missiles aren't tremendously powerful - 6d6 iirc - but they are very helpful for swarms of weaker or weakened enemies.
