There seems to be a lot of misconceptions about how to set up Mastodon.

1. You do not have to sacrifice a duck. Any waterfowl will do.
2. The bit about dancing around naked in a forest glade? While dancing is fun, you may just walk.
3. When the demon appears, you needn’t chant in Latin. It is fluent in all languages.

The rest of the guide is correct.

Not true! The demon I summoned didn't fancy KFC, muttered "vehemenaces" at me, flexed a bit and demanded I order from Swiss Chalet. It had a barely passable knowledge of Cornish, though its command of ancient Sumerian was quite lyrical. Me thinks it was newly spawned to Mastodon and had yet to get its dainty little cloven toes "wet" or more than just a wee bit worn. Waiting for my Amazon" Amulet of Multiple Resurrections"(tm) to arrive before I attempt The Guide's advanced recs.
