We cannot examine yellow/blue/green item and use a slider to see how they evolve when gemmed. I assume that each them increase all the stats by X%, byt waht is X?
I don't know if the % is constant, or not. But - for any piece that has been discovered, you can look up all the versions yourself on EQ2U - as they show up as separate items. For example: Silt Covered Chain Boots (Blue), with 1,2,3,4 gems... http://u.eq2wire.com/item/index/2252308182 http://u.eq2wire.com/item/index/457634824 http://u.eq2wire.com/item/index/2143833232 http://u.eq2wire.com/item/index/4207208437
Still like to have a slider, love EQ2U but I'd rather not be looking outside of game for all my answers when deciding on gear choices.
