Another solid article - Strongholds

As for Bigby's, I think its almost better served as an expansion to an existing stronghold. I can imagine the 300 square limit being used up pretty quickly, particularly if you want to have some of the "special" rooms and multiple levels. Bigby's would be a decent way to expand the stronghold though.

Our group is talking about building a large war station, and useing the bigby spell and the call fortress spell to build a 'platfrom' then call in our big guns...
