<p>Yes; it would be on-topic on this site, but the question's context needs to be clearly explained, as the folks here might not understand role-playing game terms like "vampire", etc.</p>

<p>However, I see that these terms do not get in the way of the question or in any way make it difficult to understand. So, you can omit those terms and ask the question as a pure statistical dice probability question.</p>

<p>And yes, <a href="https://stats.stackexchange.com/questions/tagged/dice" class="post-tag" title="show questions tagged &#39;dice&#39;" rel="tag">dice</a> questions are very well on-topic here. </p>
