Amigo como meu servidor tem vocações diferentes da normal pode me ensinar a configurar este npc?

Quando vou sumonar o NPC pelo /n da este erro :

 

[07/02/2015 10:16:40] [Error - LuaScriptInterface::loadFile] data/npc/scripts/vocation.lua:1: unexpected symbol near '<'

[07/02/2015 10:16:40] [Warning - NpcScript::NpcScript] Cannot load script: data/npc/scripts/vocation.lua

[07/02/2015 10:16:40] data/npc/scripts/vocation.lua:1: unexpected symbol near '<'

Essa é a variavel que armazena o número da vocação, é só trocar os nomes por exemplo sorcerer, paladin etc.. e o numero da vocação:

_state.n2 = 3

Não é para adicionar na pasta /scripts, esse é apenas o .xml do NPC.

 

Oracle é um NPC diferente, não tem script. o Script todo está no .xml na pasta NPC. É só criar lá o NPC com esse código ai lá dentro.
