Devouring Orb passive doesnt need further explanation can easily be seen in the screenshot but if the link doesnt work anymore, short description: The Node LEFT to the Node called “Fleeting Orb” (wich is in the Lower Right side of the devouring orb tree) has its numbers mirrored and doesnt give any tooltips.
also aparently there are no void rifts with erasing strike? or im just misunderstanding said rifts and their of instantaious nature rather than a lingering effect by nature.
