Question about The Cards Arsonist - My Arsonist targets a Building of my own principality because a “6” is rolled. But I only have Buildings that are protected by a Fire Brigade. Do I have to draw a Building Card into my hand anyway?

Answer

No.

Note: The Fire Brigade belongs to the theme set "Science & Progress", which is part of the Catan Card Game – Expansion Set.
