I'm creating my first home brew campaign for 1st level characters and while they're tracking some baddies into the woods I want them to have a non-combat encounter with some faerie dragons who aren't particularly hapoy about our heroes being in those woods. I figure there will be some illusory puzzles for them to solve to appease the FDs. If they fail they won't be able to take the long rest they will badly want before pushing through to their next battles. Looking for some thoughts on what i should throw at them.
As a reminder the Faerie dragons can cast
1/day each: color spray, dancing lights, hallucinatory terrain, mage hand, major image, minor illusion, mirror image, polymorph, suggestion
They also have Euphoria Breath (Recharge 5-6). The dragon exhales a puff of euphoria gas at one creature within 5 feet of it. The target must succeed on a DC 11 Wisdom saving throw, or for 1 minute, the target can't take reactions and must roll a d6 at the start of each of its turns to determine its behavior during the turn:
1-4. The target takes no action or bonus action and uses all of its movement to move in a random direction.
5-6. The target doesn't move, and the only thing it can do on its turn is make a DC 11 Wisdom saving throw, ending the effect on itself on a success.
