Angry Unicorns are monsters that only appear during A Soul's Bane quest, or afterwards, in Tolna's rift.

During the quest, they can only be killed with the Anger sword, which the damage done on them is multiplied by 10, with a maximum hit of 1,250. During the quest, killing one will fill up the "rage" gauge.

Angry unicorns can still be fought after the quest. Unlike other 'Angry' monsters, however, the angry unicorn does not count towards a Slayer task.
