Natural Attacks and Passive Actions

When choosing the Attack action in your turn you can replace one or more of you attacks by the following as long as you meet the requirements:

• Stomp: Melee Weapon Attack: +(STR+proficiency) to hit, reach 5 ft., one target that is prone in the ground or that is two (or more) size categories smaller. Hit: (1d(size die) + STR) bludgeoning damage. You step on a creature. If the target is two (or more) size categories smaller it must succeed a DC (8+STR+size modifier) Strength or Dexterity saving throw or fall prone to the ground.
• Crush: Melee Weapon Attack. Requires being prone: +(STR+proficiency) to hit, reach 5 ft., one target that is two (or more) size categories smaller. Hit: (1d(size die) + STR) bludgeoning damage. You crush a creature under one of your hands. The target must succeed a DC (8+STR+size modifier) Strength or Dexterity saving throw or be grappled.
• Body Slam: Requires a running jump: You jump into a space occupied by one or several creatures of your size category or smaller. The creature(s) in the space must succeed a DC (10+(STR or DEX)+size modifier) Dexterity saving throw or take 2d(size die) bludgeoning damage and be knocked prone to the ground in the closest unoccupied space next to you. On a successful save the creature avoids you by moving to the closest unoccupied space next to you. If every creature in the space succeeds the save you fall prone to the ground instead.
• Tail Swipe: Requires a muscular tail (Duh): You swipe your tail in a (5*(size modifier))ft arc behind you. Any creature in the space must succeed a DC (8+(STR or DEX)+size modifier) Dexterity saving throw or fall prone to the ground. (An arc is a flat cone)
• Restrain: While grappling a creature, if you have an additional free hand, you can make a second Grapple attack against it. On a success the creature is restrained. While restraining a creature in this way both of your hands are occupied.
• Throw Creature: While restraining a creature, if you have enough strength to lift it, you can throw it as an improvised weapon (or half that distance upwards). If the creature is two (or more) size categories smaller than you it can be thrown from a grapple instead of a restrain. A creature thrown this way against another creature or a solid object takes as much damage as if it itself was the target of the ranged throw attack. A creature thrown upwards takes the appropriate fall damage. The thrown creature must succeed on a DC (8+STR+size modifier) Dexterity saving throw or land prone.

Passive Actions are effects that apply to other actions whenever the conditions are met:

• Trample: Whenever you move through a space occupied by enemy creatures that are two (or more) size categories smaller than you, you can chose to trample them. While trampling, every creature you move through must succeed on a (10+size modifier) Dexterity saving throw or take 1d(size die) bludgeoning damage and be knocked prone. A creature can only be trampled once per turn, whether it succeeds the save or not. Enemy creatures still count as difficult terrain.
