Blasting Staff Trait
It works for everything besides Meteor Shower. Meteor Shower is also the only skill out of the bunch that does not have a Radius listed. It has a Damage Radius and a Storm Radius instead.
In the attachment, the left is without Blasting Staff and the right is with Blasting Staff, both are for Lava Font.
That’s really odd, it’s not doing it for me, its the same for both.
