1º Sorry for writing in English, I dont know Portuguese...

 

2º For the first system, do you prefer to be used a storage or a SQL Table.... Storages are a lot, but they are limited, table is not....

 

3º For the second system, how will them get the vocation? I mean, by action, talkaction, npc, door or other system? Thank you....

 

 

I will help you if you answer my 2 questions....

o jogador só vai poder escolher uma vocação e depois não vai poder trocar mais?

e seria por talk ou npc?

Well, Vodkart make it first....

 

But Vodkart, maybe you dont need to use 3 storages... You only need to calculate lost experience by maths and then register it in 1 table or storage....
