[[Mortar]] is a [[Boss Modifier]] that spawns on Bosses and Champions in Diablo III. Mortar enemies emit a steady stream of high-arcing bombs, which auto-target any hero outside of melee range. The modifier is meant to be tough for ranged attackers, as a counter to all of the boss modifiers that are much more dangerous at melee range. There is a "dead zone" close to Mortar bosses that no bombs (are supposed to) fall in, thus making them safer in close... safer from the mortars, at least.

Ranged attackers need to learn to move after every shot, (if not more often) since Mortars are launched at the current location of the hero, and standing still is a sure way to get blasted by these projectiles.
