In the script, you can choose one of 7 types of attacks. And it is not necessary to strictly correspond to their names.
For example, you can set the attack type - "Bullets", the shooting method - "Spawn Bullets", then add magic effects and you got a magic weapon. Just use your imagination and you can make many unique weapons.
Also, you can add a few attacks in one weapon. To do this, click the [Add a new one]button.
During the game, switch between attacks by pressing the [T] button, you can edit it in the Input Manager(Tools -> USK -> Project Settings -> Input).
