Game crashes due to Legendary item - DUSK VIGIL ASHEN STAFF

The game crashes due to the Legendary item Dusk Vigil Ashen Staff, within 5 minutes the game shuts down when using it, when I play with a normal weapon, no problem

Same. Using Dusk Vigil as Bloodmage. Game crashes to desktop randomly when using the firebolt+Ember fusillade skill. If I'm in a group the game crashes for the entire group.

EDIT: Crashes always when you take damage from any source while Ember fusillades are at full stacks.
