Class-specific weapons

Hello everyone.
I have ran into a bit of a problem whilst developing my game.
At the start of the game, the player can choose one out of three classes: knight, mage or paladin.
knights should only be able to use weapons such as swords, mages should use staffs and paladins should be using axes.
When the game starts, the player is talking to someone who should give them their weapon. however I am not sure on how to get the person to give the player a weapon depending on which class they have chosen.
Any help is appreciated!

conditional branch, actor, class

That's exactly what I needed, thanks!
