Hybrid games are now allowed on Myth Weavers without permission. A hybrid game is defined as a game that may be played through other means, but which uses Myth Weavers resources such as sheets or an OOC forum.
Games which do not utilize Myth Weavers resources in any manner are still prohibited and ads for such will be removed.
Alternatively, I prefer how savage species does it, breaking down all monster HD and LA in one-level packages. Even better would be to make your own monster levels where you spread out the abilities over more HD, but you have no levels without HD, so HD = lvl.
