@zudensachenSuggestions for strange trinkets to be found on wandering monsters or in lairs in tonight’s 5ed game of Isle of dread? @mikemearls pls RT shrunken head with eyes that sometimes move; tooth from an unimaginable huge dinosaur; one quarter of a treasure map — Mike Mearls (@mikemearls) September 19, 2014

@Morrus @Trevor_WotC The CR index is in the DMG (and an upcoming PDF) with the other encounter-building tools. Also monsters by environment! — Jeremy Crawford (@JeremyECrawford) September 19, 2014
