Magus is a suffix that can appear on Magic and Rare Items. It provides a moderate increase to Cast Rate.
It doesn't start spawning on items until Item Level 29.
This does not apply to combat but instead only those skills that use a Cast animation. An example of this would be Fire Bolt or Inner Sight.
Faster Cast Rate items can stack.
