One of a small number of the potentially dangerous creatures to appear in Fantastic Beasts & Where to Find Them is of course the massive erumpent. These enormous beasts have some resemblance to a rhino, but they are even larger and their horns produce a highly explosive fluid. Despite their intimidating appearance these creatures are truly gentle giants who only attack once provoked. When driven to defend themselves however they are extremely deadly.

I designed them to be physically powerful, resistant to most common forms of damage, and capable of dealing out a great deal of destruction when they’re of a mind to do so. I’d advise GMs to use them like a wrecking ball. Tear up the scenery, break down barriers, and blow stuff up. The erumpent will probably flee or give up a fight it seems to be losing unless defending one of their young.
