How to tame Antrodemus on an ASA unofficial server

First: Clear area of all dinosaurs.
Second: Craft brains in your inventory with Allosaurus brains.
Third: Throw out the brains at a safe distance. (May need to use multiple brains)
Fourth: Once it eats a brain it will glow with colors. Go ahead and start attacking it.
Fifth: Bring its health down to roughly 10% and below. It will automatically knock out for you.
Once knocked out use its favorite foods to tame.
