Good Quilas
The Good Quilas may be worn by male Archers who have gained one or more Abilities. This armor can be found at the Asilon Armory on the continent of Medenia.
To become an Archer, the first thing necessary is to be a master Rogue, with all 4 creant quests completed. When advancing to become an Archer, the Aisling must sacrifice his master equipment, and his grand master equipment. As well as much of the experience he has gained so far, along with some health and mana power.
Very detailed information on the new paths can be found in the Library, for priests at Kayson's Site for Priests and for gladiators at Vamistle's The Warrior.
