Fight the Power
Fight the Power is a quest given by Oscar when you become friends with him. The quest will begin by Oscar complaining about a supposed vandal in Staxel, and how he believes Maximilian is not doing enough to stop them, or even is the supposed vandal.
But we can't do this alone! Aliza knows how to make excellent signboards.
Oscar wants the player to go to Aliza to ask about signboards for his campaign. Aliza will give you the recipe for Oscar Campaign Signs.
Now, I think a decent first batch would be about 10, wouldn't you say?
