Good Talma
The Good Talma may be worn by male Summoners who have gained five or more Ability levels. It is basically a dark green floor-length robe, accented by a white mantle with cowl and a dark leather belt. This armor can be found at the Asilon Armory on the continent of Medenia.
To become a Summoner, the first thing necessary is to be a master Wizard, with all 4 creant quests completed. When advancing to become a Summoner, 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.
