Hello,
I purchased 20 turquoise and made two turquoise rings, but only one came out with 5% SSI. Does anyone know what the %'s are for crafting a turquoise SSI ring?

I'm not sure the percentage, but one out of two was lucky...I think I burned through all my turquoise (probably about 200) and only got one with SSI that was also full of useless mods.

Edit: I looked it up, and UOGuide says it has a 5% chance.

Faster Cast Recovery 1
Lower Mana Cost 5%
Swing Speed Increase 5%

Not the best mods, but since both my archer and necro count on mana and continual casting, not really too bad.

Figure I can imbue some nice things into it for the last two things.
