Greater Arson question

Effect: Destroys up to a max of 6% of targetted enemy buildings at the rate of 0.0045 buildings per thief.

Does this mean 6% of 100% of their land, or 6% of a single building (15% of their land for example), or 6% of multiple chosen buildings?

Makes more sense for the targeted building. ie. 100 homes, max 6% would be 6 buildings.

[Kayani]

I'd really like to know the answer for sure, too, though I think Faye is right.

This. You target a specific building.
