I'm having an issue where the Chilled spawn with the "Molten" modifier from the Champion Mobs mod. This makes them fire immune, which, combined with Consecration, makes them almost impossible to kill without a consecration splash potion. Not sure if this is intentional, but it is annoying. Thanks for a super fun modpack!

Will look into the config to disable Molten as a patch fix, hopefully I can come back and balance champion/Apotheosis boss mobs at some point.
