Allosaurus's Axe Bite ability
i think the Allosaurus should have what made it famous, the Axe Bite. The Axe Bite could be the Allo's secondary bite attack just like the Daspleto's bone crush bite.
The Axe Bite can cost 1200 marks, need the Allo have to reach at least sub-adult stage to be able to unlock it.
It will deal medium damage with a huge amount of bleed damage, and it will also have 4 seconds cooldown just like Daspleto's bone break bite.
I think with this Axe Bite, the Allosaurus will be the carnivore that have the strongest bleed of all carnivores, just like how Iguanodon have the strongest bleed of all herbivores.
