This is a big creature. Unfortunately, it also uses some very rare pieces. Quantity x Scarcity = Priciness.
We always try to keep our monsters affordable, and this is the first one that has truly gone well beyond what we had hoped. (lol, just wait until we finish the Tarrasque...)
But we built this anyway because our goal is to create every creature there is from the main D&D books as well as the main PF books. So here it is!
