So I'm running a campaign for my girl friend and it's a big sandbox with some of my own adventures and some of my favorites ones. It's got some of Phandelver in it and she wanted to kill some goblins, which led her to this castle. I read the adventure once through and then went through and took notes on the map in microsoft paint.
I think this is how I'll do maps from now on. I'm going to try to key one with just text in the rooms and still have enough room to put loot tables and the such. See how it goes.
(short post today because I just wrapped up writing a new adventure and am exhausted and just want to jump around as Winston in Overwatch)
