Demons of Greed are children of Mammon. They look like oversized amphibians, but they will have heads made of expensive metal such as gold or silver. They may also have augments made of gold, etc. If the amphibian that the Demon is based on doesn't normally have the part, that part will be an augment. For example, since frogs don't normally have wings, a frog-like Demon may have golden wings. Since newts normally have 4 legs, a newt-like Demon with 6 legs would have 4 natural legs, and two of them could be made of silver.
