I’ve mentioned Kickstarter, and Patreon, a few times in the past. For those who aren’t that familiar with them, what both of those, and others like Indiegogo, do is reduce the risk for making products. Essentially, you are getting a guaranteed income rather than a potential one. The guaranteed income may be lower – but if a product doesn’t work out it will actually be higher. So, lower risk.
The vampire bunny is a monster that appears in the Rolemaster Creatures & Treasures supplement, which is available as a PDF and print on demand book from RPGNow in the updated version, Rolemaster Classic: Creatures & Treasures, or as the original print edition from Amazon. This creature is not described in the Vampires section of the original book, and only its stats are listed.
Here is an ecology article on the vampire bunny, presented in the manner of the original ones found in older issues of Dragon Magazine.
