I'm in the part where I've got 90% of the work done, and the remaining 10% is the other 90% of the work! There's a few final bits that have me stumped for wording and formatting, so progress has been super slow. I'm also grappling with trying to elegantly implement more accurate attack rules (it's based on weapons, not mounts), which I don't consider solved yet. But I'm glad you're looking forward to it!
