Skillspell book

You can easily assign an attack or spell to your right mouse button. Open your Skill Page by pressing the associated icon in the bottom interface or simply hitting the K key. Left click on the spell you want to set and it will be mapped to your right mouse button. You can also assign a hot key to any of your "Active" spells by placing the mouse cursor over the spell and pressing F1 – F12. This will bind that spell to that key, allowing you to call it up instantly as your right mouse button skill.
