we've got a few books now, that scott made up and posted in the Downloads section. the new format, with the elementals and now yugoloths, is really nice. which grouping of monsters do you want to see in a book? something that you don't see here? well, post it below!
i was thinking about that one, but there aren't very many on the site right now. maybe in time, we'll have some more (there are more unconverted than you may know), and we can put that together.
Please ignore the post by madriel above (I was logged in under my GF user name - d'oh!)
I voted for plants - given the campaign I'm currently running (see the "Hangman Tree" thread for a few details) I need more plant monsters! Everything I make involving plant life just seems like a half-a**ed treant
i'm going to have to re-post the Searechter soon. basically, it's the marine version of the Spectator. sort of like what the Eye of the Deep is to the standard beholder.
On a realted (well somewhat, they're both aberrations ) note, any chance of anyone doing a conversion of the Elder Brain. It's a little hard building a mindflayer city/campaign without it.
Bear in mind I haven't looked around much, but if you have enough Fey creatures, it would be useful to have those. I mean, there are only 5 fey in the entire monster manual, even though the fey are integral to European folklore.
