From a blog post about 13th Age:

13th Age keeps a d20 skeleton, but deliberately makes concession to fiction.  This occurs in class design at multiple points, but really shows up in monster design.  I want to introduce you to the best monster in the 13th Age book, the Owlbear, and one of its abilities:

Feed the cubs: An owlbear that scores a critical hit against a  hampered enemy tears a piece of the creature off (GM chooses a limb) and will subsequently attempt to retreat with the prize to feed its cubs. The torn-up enemy is stunned until the end of its next turn.
