Yeti. The very word strikes terror in the sturdiest and most valiant. And that's just one of them. Imagine if a blighted place, such as Frostgrave, had more of these things infesting the ruins? They're big. They're horrible. They eat anything and everything. They're best avoided. Unfortunately in Frostgrave's treasure filled ruins that simply isn't possible. Depending on a D20 of course!
