Looking to mix up your dragon fights? Why not throw in a linnorm, a species of dragon based on Scandinavian lindworms.
An ice linnorm is a CR 17 dragon. Like all linnorms, it has constant freedom of movement and true seeing, as well as a death curse that activates on whoever kills it. In this case it’s a Curse of Frost (Su), inflicting a weakness to ice damage on the target. For offense it has a breath weapon of freezing slime that entangles and chills targets, congealing into ice if they don’t manage to escape one round later.
When looking at linnorms there’s two main things to take into account: 1) they’re older than dragons, and 2) they’re largely forgotten by the world at large. No dragon likes being ignored, and when that dragon is older that those upstart chromatics and metallics who go around like they own the place? Things will get messy.
Linnorms have existed for ages past, living to see the rise and fall of entire eras. The oldest have seen not only the nations of men and elves but what came before, empires built by beings from the stars and collapsed by their own disobedient servants. Such linnorms are all too happy to tell adventurers of the shapeless things lurking in those ancient ruins, hoping to lay claim to the few structures older than themselves once their current occupants are slain.
In a land of extreme temperature changes, it can be difficult to lay claim to a particular region. Ice linnorms rule the freezing nights and polar caps, but with the planet constantly rolling on multiple axes, they must frequently hibernate and cede their territories to the heat-craving salamanders, only to reclaim them in bloody attacks when the temperature falls once more.Â
Political maneuvering has seen the heir apparent faced with a daunting challenge: slay the ice linnorm that preys on the northern reaches of the kingdom. Should they fail, their political adversaries will leverage that to tear down their standing, while success will subject them to the death curse and make assassination attempts much easier.
