are you using the attached list_skills.stb?
what client are you using... h-rose, B-rose, I-Roseph, Ruff, Ect.....
what version of rose are you using.... Evo, I-rose, P-evo
The Fairys have special skills created for them in the list_skills.stb
the new fairy was created using the List_npc.stl (name), List_NPC.stb (data), List_NPC.char (model) and the AI files...
then the AI was created to telling the NPC to use the Buff.. and the ai to link to the game to be used is to the list_npc.stb
thats all the STB, Stl i gave you.... and all are necessary.
if you using an different client to h-rose it might not work.... but could add the skills to the fairys ya self..
Alittle info about the client you are using would help me... help you..
