Good Casin
The Good Casin may be worn by female Druids who have gained five or more Ability Levels. Much like the early bodices for Monk ladies, this combination of short, wrap-around leather skirt and metal bodice with metal arm braces allows for great ease of movement. This armor can be found at the Asilon Armory on the continent of Medenia.
To become a Druid, the first thing necessary is to be a master Monk, with all 4 creant quests completed. When advancing to become a Druid, the Aisling must sacrifice her master equipment, and her grand master equipment. As well as much of the experience she 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.
