I'm a new dungeon master, and I ran into the problem that I didn't know how "generating ideas for delves" works. I've used delve draws for this, and I'm very positive about it! I'll leave a more elaborate review once I finish my campaign.
Next to that, I just want to tell you how much I appreciate Sillion and Brendan's work. Heart is a magnificent game -- it deserves all the supplements in the world -- and you set a great example. I hope much more follows.
