I'm setting up a big D&D campaign and I want to use a whole lot of miniatures for the fights. The only problem is that D&D miniatures come randomly packaged and they dont make all of the creatures I need. So, I'm mostly getting LOTR and Warhammer miniatures, but I can't seem to find any dragons without riders or any sea creatures. Also, I need a frost worm and a vampire lord. Any suggestions to my situation?
