Just to add some words of warning perhaps to the 'receivers' or 'creators' of the items: first, many of these effects can be realized as spells on the items, having limited amount of charges per day. Easy to do. But, you all know the Cowled Wizards in BG2. So when your "Lord of the Rings" party is walking like big mojo's in Athkala and start a fight with some band of muggers on the streets, and want to show of your flashy effects.. Let's just say that you will shortly and soon have a fight on your hands with the Cowled ones. Sure some spells are only clerical ones (and Cowled ones don't care about divine spells), but not all
So you will be either forced to pay 5000 gold, or fight the Cowled ones (which I always do, after few levels though). Just be careful with yer effects and spells on the items
And yes, I could also make all these items, but no, I haven't got the time for this. Busy life.
