Found these in a printout, probably from my world stack...
Potion of stat swapping - DEX or AGI and WIS
Cursed sword of increasing fumbles
Ring of Rings - On request roll CHA as a percent and get ring power of choice(short of wish), else get random ring power, works once per hour
Golden Dragon - usable once per day, becomes an adult gold dragon for 2D6 turns. Each time the dragon gets a small percentage save to break free and remain alive and independent. This is not revealed in basic understanding of the artifact. It's attitude towards the item owner will depend on how its been treated at summoning.
