Worshipper – “Conquest” [Campaign 2, Mission 3]

It must be Air Week.

I had a week like that once, it was rough. If you don't have many knowledge points, you won't be able to use mana much, it's the same as having Reckless Week, when the experience gained in battle is reduced by half. You might as well just lock yourself in the castle for the week and not go out, because there's nothing to do)) unless you have free resources collected.
