On an attack roll of 15-20, if the attack succeeds, the victim must succeed on a Strength or Dexterity check (its choice), DC [10 + the creature's Strength modifier], or be Knocked Prone. The creature reduces all weapon damage it takes (melee or ranged) by 2 (damage reduction 2). Spells deal normal damage.

The creature uses its great size to affect several creatures in front of it with a single blow. If multiple targets are in front of it, its attack affects two creatures (in a 180° arc). Make a single attack roll and compare it to each target's armor class. Its damage reduction increases to 4.

On an attack roll of 15-20, the victim is thrown [1d6+1] meters away (more or less depending on the size of those involved) and takes an additional +3d6 damage. It must succeed on a DC 15 Constitution check or be Stunned. Each round, it may attempt a new Constitution check to regain its senses. Its damage reduction increases to 6.
