Take something that already exists and describe it as something new. Let’s say we want a powerful barbarian bodyguard for the evil baron, but don’t have a great bodyguard stat block handy. So instead of building a new monster stat block, we can use the stat block for an ogre and describe it as the baron’s bodyguard. One memorable encounter setup, done! Reskinning monsters is likely the most popular use of this technique in tabletop RPGs. But the same technique works for dungeons, towns, cities—even entire campaign worlds.
