On paper, badgers are not threats. But no player would want to corner a badger (let alone a dire one), so that’s just what you should make his or her PCs do.
A witch’s patron has sent her a badger familiar. She soon finds its ability to burrow handy in delivering touch spells.
For such small creatures, a band of pixies can be challenging foes. But most pixies never need to nock their arrows. Instead, they use dancing lights to introduce assailants to the nearest dire badger.
A trap spills caltrops across a party’s path, then drops them into a pit that is home to a clan of dire badgers. Already feeling threatened, those badgers damaged by the rain of caltrops go into a blood rage.
