[FIX] You need to buy spells to be able to use them.

[Eldora]

How can i fix that you need to buy spells from a NPC to be able to use them?
I have forgot how to enable that.

Using Avesta, anyone know?

I dunno how really, but i know in Spells.xml there is an option [learn; yes/no] cant remember how its wrote ;p

 

[mijnoma]

in spells.xml turn needlearn to "1". This means you need to learn the spell before using it.
Then you gotta config an npc, item or whatever you want to learn the spells.

example of the npc in case you didn't have one yet
