Calamity track
From Wildermyth Wiki
Many calamity cards introduce new monsters or increase the number of monsters that spawn within a mission. These cards can only be drawn if the associated faction holds a number of calamity cards that meets or exceeds some threshold. In this way, each faction has a calamity track consisting of successively more dangerous cards.
Table
If drawn within a mission, each card typically generates a number of the specified monster equal to the card's roman numeral. There are some exceptions, which are noted in the table. Also, italicized cards are not drawn as calamity cards but are instead available from a campaign's outset.
