Genie~ Was from the 2nd expansion way back.
You get it at lvl 1 from an NPC in every major city, "Watcher of the Earth", and you randomly get one of the 4 types of genies, Infliction (Pink, STR) Zeal (Yellow, MAG) Longevity (Green, DEX) and Discipline (White, VIT). They get one basic skill at lvl 1, and then u can customize them by going to the same NPC and getting other skills once ur genie lvls (you can use EXP stones on it or infuse it with ur Spiit so it can lvl faster) some skills are class restricted, but most aren't. Second Wind, the heal, is really helpful especially if you add lots of STR and have Infliction as well. and also Zeals basic skill is a great puller :P (i think..)
With 3 mirage stones u can choose any genie you want from the NPC, today I changed mine to Infliction for better healing xD Its skills use stamina which you can regenerate with Chi stones~ Not sure if they had supply stashes when u played but at some point u get 500 chi stones from it, and you can always use attendance cards from PW teacher and get 1 card for 1 stone... but I'd rather save up for rings xD
