1) If you happen to have that shield that cancels the food cost on every third tile, and it triggers when you land on the Far North brimstone card, it will negate all the food costs for that entire encounter. I was able to brute force the 18 roll without any dice buffs like this.
2) If you run out of time in Raider Prevention while aiming something (the anti-mage daggers in my case), time stays slowed down while the resolution animations play, and then it stays slowed for some of the loading screen, taking several minutes in total.
