Well, considering that getting Wolf Tears to earn Topaz Coins is hard sometimes as I cannot find a party to go in and farm.
So if the level of the enchant is like 3 or higher I should keep it if it's DURA is like 190 ~ 220? Besides I need just Stamina and Luck for the sets right?
Except Critical Damage on Gloves and, maybe, Movement Speed on Shoes.
EDIT: Here's the stats of all of the Coliseum Gear I've collected.
