Shoving is where a character tries to shove an opponent from the current grid into an adjacent grid, possibly bumping another character.

The shove is executed using the GRM:

Attack Level = (Strength Bonus + Character Level)
vs.
Armor Class = (Dexterity Bonus + Character Level)

If the attack succeeds the defender is shoved 1 grid into the opposite grid from the attacker's direction. If anyone is in that grid they too can be accidentally shoved. In this case the defender is the person inside the hex into which the first shoved character is being shoved, but the original roll for the shove is used as the Attack Level while the Armor Class = (Dexterity Bonus + Character Level). A Critical Hit for a Shove adds 1d6 /2 to the number of grids the shoved Character is moved.
