Up next is the Bears. Black, Brown/Grizzly, and Polar are already done in the 5E MM so no need to do them. The RC also had a Cave Bear so that one is the only one I needed to do. As an observation, it appears to me that normal animals in 5E are not as powerful (relatively speaking) as they are the RC, so in general I have taken that pattern and reflected it in my conversions.
CAVE BEAR
The cave bear is an ancient and rare species of bear, reaching 15' tall when standing on their hind legs. They are usually found only in very remote regions, especially in areas seemingly untouched by time. Possessing a patient determination, and a good sense of smell, a hungry cave bear will follow a blood trail until it has eaten . Unfortunately, they have poor eyesight which can hinder them sometimes. The cave bear has a preference for freshly killed red meat. When having to provide its own meal, the cave bear tries to pin their prey to the ground, employing as much of their weight as they can while biting. As their name suggests, they usually live in caves.
