Heroes of the Realms
SHOVING A CREATURE: Special melee attack to shove a creature which either knocks it prone or pushes it away. The target must be no more than one size larger and it must be within your reach. You make a STR (Athletics) check contested by the target’s STR (Athletics) or DEX (Acrobatics) check (the target chooses the ability to use). If you win the contest, you either knock the target prone or push it 5 feet away from you.
