With a strength of 3B 2G and a will of 2R 2G, Krampus is well-equipped to destroy any Hero. It has a lower armor than most dungeon bosses, but this is compensated for with its abilities.
You’ve Been Naughty shapeshifts any Hero that scores a critical against him into a Naughtie, turning his low armor into a potential asset as Heroes are more likely to score criticals. Once some Heroes have been transformed, Nom Nom Nom! allows the Krampus to heal whenever he destroys a Naughtie.
The first action available to Krampus is Into The Bag. This devastating attack renders the target Immobile and Hexed, making its next activation difficult as it struggles to move or attack (it’s hard to move when you’re stuck in a sac, after all).
The next action is the Grabbing Stick, which allows Krampus to move the target with compel, potentially setting it up to perform an attack for the Consul because with the final action, Make Mischief, the Krampus can force the Heroes to attack each other if they have been turned into Naughties!
The Krampus's Boss Fight card help's ensure that at least one Hero will always suffer the fate of being transformed into a Naughtie thanks to Caught Red Handed. This ability also provides a fun interaction with Kringle's own Nice List ability. Run Free, Children turns the Heroes upon themselves, allowing the Consul to use Naughties to attack the party.
