Iguanodon Bull

A heavy plant-eater the size of an ox, armed with spiked thumbs it drives like daggers into anything that threatens the herd. Placid until cornered, a bull iguanodon fights with surprising ferocity. Great herds browse the river valleys, and when a predator circles the bulls form a bristling outer ring of thumb-spikes - a bull defending calves turns single-minded, driving its spikes home long after the threat has stopped moving.

Thumb Spike: piercing, melee 5 ft, +1 to hit, 2d6+4 piercing. Tail Lash: bludgeoning, melee 10 ft, 1d10+4 bludgeoning. Goring Stab: it drives both thumb-spikes into a held or prone target for an extra 2d6, cooldown 2 rounds.

Herd Beast: +2 to attacks while another large herbivore is near. Sturdy: +2 to saves against being knocked prone or moved. Senses: Vibration Sense (feels movement, 30 ft), Dark Sense (30 ft).
