for a start there is a bar were you can fire sells, and a tiny spell book that holds 4 slots, The spell books size should increase.
Not sure what you mean.
secondly mabey make some spells hidden for each class for instance if your warrior when your start, the heal spell is not on the action bar
Then just don't give them the spell.
mabey you should be able to get some spells through clicking a use once item?.
Would be easy to by yourself.
Don't think I'll put this in directly.
skills requing items, Skills at the moment cost mana, I think it would be cool if you could make other costs for instance items.
Again, easy to add yourself.
