ToME: the Tales of Maj'Eyal

I just found one, at spawning depth, with my lost soul deathmold alchemist.
I couldn't find this one in the spoilers.
What does it do? I don't want to use it to test, not until I've found a scroll of *identify*, to get the recipe.

It will give you a random good piece of equipment. Since you can make better stuff than what it will give you... Read it!

It gives you an excellent piece of equipment, not good (the randart gives good stuff).

You will never want to make one, so don't worry about *ID*ing it. Extract it.
