i designed a dexter character around one with heavy overall skill increase, 100 damage inc on suit. its a good jewel, but very hard to use. hardly anyone uses them. theres so many out now, especially since we got the doom stuff again this year instead of something different that there worth very little. they were average 20 mil when we didnt know if we would be able to get them again, now id say around 5 - 10 mil.
