It really isn't. The active is pitiful, very situational and unable to use to fullest extent. It's also useful for a short time period before an enemy can just burst it with basic attacks with ease.

The passive only affects the on-hit and not the beam so you're better off investing into raw AP than the 15% aura.

It does give CDR and AP but there's better items for that, ie Morellonomicon and Athene's - you know, items that actually help you spam your abilities.
