To learn something about the TrinityCore scripting system and c++ i wrote a npc to change faction/race or make a customize of a character.
The gossip menu has following options:
How many Faction Changes are possible?
How many Customizes are possible?
How many Race Changes are possible?
I want to change my faction!
I want to customize my character!
I want to change my race!
The count of possible race/faction changes or customizes takes the npc from the account database.
