Copper Dragons delight in luring adventurers into their territory by letting the sun hit their scales to entice treasure seekers to follow them on a fool's chase.*
"Adventurer, trust me, and stock up on some jokes, riddles and funny stories. They might one day be your only chance to escape from a Copper Dragon's lair."
Most seasoned adventurers abandon their chase as soon as they realize what they're chasing, with only the dragon's booming laughter a reminder of how they avoided certain death. However, bards, with their nigh-endless amount of riddles, jokes and songs, have on average a fair chance enter and leave a Copper Dragon's lair unscathed due to these magical monsters' love of entertainment.
