KEEP THIS POST ALIVE!! Queens and razor queens are completely random. You are not guaranteed one at the end of a nest, and they can appear at the end of any nest. Razor queen will only appear if you have a complete beastiary. If you are actually looking for one of them, the best approach is to kill a small nest down to 10 or so glooples and then just dodge and wait. Eventually a queen, razor queen, or amalgam will show up. I usually leave a relatively large number just in case of an amalgam because that can eat up 3 or 4 of your glooples just to get rid of one of them, and then you won't necessarily have to start over. Hardcore mode will not help anything, so use it if you like it better, but it's not going to increase your chances of a queen or razor queen spawning. (origonal creater me)
