Last weekend I was finally able to run my first game of D&D, and it was a success
I made my own adventure, and I was a bit frustated at the tresure selection. I mostly just hit the random button on asmor.com until I hit some items that I liked. I recently got the Rules Compendium and I wanted to use the rarity rules, give them more common stuff, and some uncommon stuff on later levels. However it isnt clearly defined what actually would be uncommon, common, or rare, there are a couple of examples, but thats it.
So my question to you, is how do you determine the rarity of items?
-Do you just say this item is rare, this item is common, and thats it?
-I thought about using item powers as a reference. If it has a power its uncommon at least.
-I know that Essentials rules are not in the Char Builder, but its a possiblity that items will include rarity stats.
On a somewhat related question: Are there item creation rules that I am missing? I could only find the Enchant Item ritual. Since it sound pretty basic I am thinking that Enchant Item would only be able to make common magic items from non-magic stuff. But how would you make lets say a magic sword direct in a forge? Useing Enchant Item while its being made would be OK for a two-person job, but how would a single player do it?
