About Shadows of Brimstone: Challenge Pack #1 – Bound by Darkness, from BoardGameGeek:
Holy preachers are renowned for their devotion and faith, leading the charge to keep evil at bay. When one of these men of the cloth is corrupted by the ruinous powers, his fall from grace plummets to depths far deeper and more twisted than could be imagined. Heretic Preachers fight with a fanatical zeal, wielding Dark Sermons to unleash hellfire and damnation on any that cross their hellbound path to becoming one with the Darkness.
Challenge Pack #1 - Bound by Darkness is themed for facing off against a corrupted Heretic Preacher and his legions of demonic and beastly minions that all use the Bound by Darkness Enemy Trait card. Casting powerful Dark Sermons at the Heroes, and wielding a devastating Hellfire Shotgun, the Heretic Preacher and his hordes will put your Heroes to the test!
A Challenge Pack is a new themed set of cards with a terrifying new Enemy and a nightmarish new Mission designed to give the Heroes an extra challenge. These cards are all used together for the included Mission; but can also be added to your card decks to increase the challenge across your normal games of Shadows of Brimstone as well. Many of these new cards are marked with a Challenge Icon, to be easily identified as extra dangerous.
Challenge Packs reward players for having a robust collection of Enemies and Expansions; and contain several Threat cards that include a mix of various Enemies from across the game. Some of these Threat cards even add new bonus ability to the Enemies on the card for thematic ways that they can work together to crush the Heroes.
The following Expansions are highly recommended to get the most out of this Challenge Pack (though these sets are not required to use this Supplement, most of the Threat cards included in this Challenge Pack do use various Enemies from these other Expansions):
Swamps of Death core set
Hellfire Succubi mission pack
Hell Vermin enemy pack
Scourge Rats and Rats Nest enemy pack
Forest of the Dead OtherWorld deluxe expansion
