I am getting ready to GM a group in August so I am doing the base line work. I currently have the games major plot devices set up, and the games 5 major bosses. One of these is an Elven Alchemist, with ties to the Technic League in Numeria who has been using a combination of tech, alchemy, and magic to create a savage new monster, known by the codename "The Beast", I realize that's a lame name and will most likely to change later on. My issue is what would he be considered Magical Beast, Construct, or Aberration? With my idea the Beast would fit all three types extremely well since he is of alien thought and biology, was constructed, and infused with magic. Just looking for ideas, and thoughts. He is meant to be one of the games higher end bosses pushing CR 19-21.
If he was constructed from base materials then it sounds like a construct. If it was an living creature altered with magic it sounds like a magical beast. It doesn't sound like an aberration to me.
Since it's a homebrew monster you can do some fun stuff too. You don't have to necessarily make it just one creature. You could have a construct with a hollow cavity in it's chest that is containing another monster, say a ooze or a worm or whatnot so just when they think they have it defeated a new encounter begins.
Well the reason I said aberration as well as it used some DNA found on the Silver Mount (I am using the idea it was a crashed ship) and using magic and tech to enhance and fill in the holes that the DNA had in it. So that's maybe why I see it as possibly all three of those types. So its a constructed alien biology and intellect infused with magic?
