None cross Greywolf and live! That one for sure. My first ever playthrough I missed the narrows that take you into the Nashkell mines, so found Prism before entering the dungeon. Then once you had Varscona it was like "fuck yeah! these Kobolds don't stand a chance!" It was also nice that they brought it over in BG2. It was one of those weapons you didn't really want to sell even once you had a better sword. Keeping it just for the heirloom status hehe. Same as like the Ashideena Hammer, holding onto it for the classic flare.

I'd add also the various robes of elemental resistance in different colors. I always held onto those as well, at least 1 set to switch into periodically. Esp the Robes of Electrical Resistance, since they had the nice red trim and looked pretty badass on a villainous fighter/mage or thief/mage as well. Sporting black and red, like Elektra style robes! lol

The Heart of the Golem dagger also felt pretty badass. It had a good and memorable name that didn't strain the spell checker overmuch lol
