Well my own work veers between Cauldron #2 and the HOW revisions, but in the meantime there is a LOT of great stuff going on and be creating and commented on by your fellow HOW fans!
Joshua Macy has commented on a number of potential options or changes to HOW that are very interesting, especially if you like a more TFT style of game! His creativity extended to creating a hex map of the Cave of Chaos map!
Tin Knight continues to share his creativity in a number of HOW posts, and especially in creating new spells!
Behind the scenes two other folks have created some interesting HOW related material that I am hopeful to make availble in the near future!
Lots of great and inspiring ideas, options and work from a lot of great folks--thank you for your continued support!
