Making this item with a CHA of 120 or over will get you 4 platinum, 3 gold in profit if you buy your components from a vendor and sell it to a vendor. Of course buying your fire emeralds from the bazaar is the smarter way to go.... :)
Looking over the price in the pricing data. I think it is rediculous that someone would sell this for less that 100pp when an indiffernet merchant will give you 104 pp with max cha (and why would you be sellng anything this expensive WITHOUT maxed cha).
If a friend or guildmate gave this to you for cost (99p7g4s1c) than MAYBE a tiny bit less than 100pp. otherwise ... what? 50pp? Are you high?
I cant think of an item at this time that I can afford and want as much as this! My bronze armor is so heavy on my Paladin, and even just one of these on my wrist is worth the price of taking up this skill... which is what trade?
The skill is jeweler. But why not just get a bracers of erollisi for someone. they sell cheap (50pp), and have +5 AC as well as +5 strength. Be forwarned, by the time you have developed your Jeweler skill to the level to make gold jewelry, you will have dropped several thousand Plat into the trade. For that price, you could buy a hero's Bracer (ac9, +10 strength, plus other bonuses) for one wrist, and the bracer of erollisi for the other, plus some extras. Of course, you'll be able to earn that plat back quickly at that point. But if your goal is just to attain this item, buy it.
