Acquire All 7 Crystals of Power (on eBay)

You are on a mission to collect all seven Crystals of Power, because that’s what heroes do: collect lost crystals. Why do enchanted rocks always get scattered across the land? That’s above your pay grade. You just find ‘em, save the world, and enjoy a lukewarm mead when it’s done.

So far, you’ve scaled Spikedeath Mountain, survived a bridge implosion, and punched a giant hand in its finger throat. And yet, you’ve uncovered none of the Crystals of Power. Where are they hiding? Suddenly, an alert pops up on your phone:

LOT OF 7 CRYSTALS OF POWER – ANCIENT/VINTAGE – NEW OLD STOCK – REAL MAGIC!!! 
1 Bids at 44 gold
Bidding ends in 60 seconds

WHAT?! How did you miss this? When the Wizard Council gave you this quest, you immediately set an eBay alert. You get every listing for “dwarven cheese axe.” There are only seconds left in the auction and you’re certain the “1 bid” is from Galzor the Malevolent! You can’t let the evil goat lord get his red hooves on those crystals, or the kingdom of Moredank will be plunged into 1000 years of darkness…

How much would you like to bid? (1 gold ≈ $15 USD in D&D land)
