Palla, I've tried before also, to make Ron armors for my mage, is very hard to farm these mats, even buying them from merchants.. And not to even talk of the success rates..
Thats why I hate so much this faggot Dudepat from deadshot corps, selling gm made sets of new armors +8..
Anyways, wish u good luck making them +7, Trial Set +7 > Chitin Set +8
