Oblivious nature: It has low perception, but every time it takes damage, roll a d20. On a 15+, that damage is ignored.

Multiattack: This creature can use both it's headswing and its tail attack in one turn.

Headswing: Melee weapon. Targets a 15ft cone in front of it. Any enemy hit in this area takes 2d6+4 bludgeoning damage. Any creature hit must make a DC 15 dexterity saving throw or be knocked prone.

Tail attack: Melee weapon. Targets a 20ft cone behind it. Any enemy hit in this area takes 2d6+4 bludgeoning damage. Any creature hit must make a DC 15 dexterity saving throw or be knocked prone.

Kick: Melee weapon. One enemy hit takes 2d8+4 bludgeoning damage. Any creature hit must make a DC 15 dexterity saving throw or be knocked prone.

Stomp: Targets a 10ft circle in front of it. Any creature in the radius rolls a DC 15 saving throw to take half damage. Deals 4d8+6 bludgeoning damage to a creature smaller than large, or 4d12+10 bludgeoning damage to a creature bigger than large. Any creature hit must make a DC 15 dexterity saving throw or be knocked prone.
