Reduce land speed to 30 feet, give it Multiattack, say it's CR 4 and I'm tempted to call it done.

Added to Homebrews.

Anyone want to throw down some flavor text?

This creature resembles a large tapir with a short prehensile trunk. Two pairs of curved tusks grow from its mouth.

A xenungulate, Astrapotherium is a member of an odd lineage of herbivorous mammals. Despite their superficial resemblance to tapirs and elephants, they are not closely related to either. Astrapotheres are hippo-like in their behavior, wallowing in mudholes and swimming in rivers in order to graze on plants growing from the bottom.

Happy belated birthday! I hope it was a good one.

Flavor text looks good. Updated.

Wikipedia says it is a little over 8 feet long. Suggested weight?

For tactics, state that they are generally docile, but capable of defending themselves with tusks and hooves?

 

[InsanePsychoRabbit]

Somewhere between 500 and 600 pounds is my guess. Tactics flavor text sounds good.

Happy belated birthday! I hope it was a good one.

I was busy all day with classes and I didn't have too much time to relax and enjoy myself, but at least it was the first birthday in three years that didn't involve me injuring myself or coming down with a nasty illness.

Edit: I saw some news about a newly-discovered enormous pliosaur. How about we do something like a dire Kronosaurus?

Updated.

Whoa..."Predator X" looks cool! Yeah, we should do a "super kronosaurus". We've got a regular one for a basis.
