This eldritch essence invocation allows you to change your eldritch blast into a beshadowed blast. Any living creature struck by a beshadowed blast must succeed on a Fortitude save or be blinded for 1 round, giving it a 50% chance to miss in combat, removing any Dexterity bonuses to AC, adding an additional -2 penalty to AC, and causing it to move at half speed. Additionally, this causes the target to be considered flat-footed (hence the removal of dex bonuses to AC), meaning that they can be sneak attacked by rogues without the need for flanking.
