Ring of Fortune
At the beginning of each session, roll 3 Fortune Die. If at least one success is generated, the wearer of the ring will increase his Fortune Points to 4 for this session.
This was given as a gift to one of my PCs by a stranger who is "helping" him. In reality, there is an enchantment on the ring that will reveal the player's location. (Not sure if that works in WH since I'm new to the setting and designing my own world anyway).
I'd be interested in what anyone thinks. I thought it might be okay as a low powered item.
