This picture has nothing to do with the campaign but let's face it. This is exactly how the players would act in this situation. This image comes from the hilarious webcomic, Wonderella.

In this episode, the heroes of New Arcadia face a seemingly invincible foe – the leader of the Crystal Children cult. His powers stop anyone from attacking him directly or indirectly so he cannot be assassinated or captured. Can our heroes devise a means to stop this powerful psychic cult leader? Aside from that, the heroes have to secure the Hellmirror, a powerful and evil magical artifact but this isn’t as easy as it seems, even though it resides in the police evidence locker.
