I've been on-and-off GMing since 2023. Over that time, I found out that I really don't like base DnD5e. I am not masochistic enough to try any of the older versions, Pathfinder sounded fun, but nothing really clicked.
And so, I designed add-ons and made interesting bosses for my players that added to the main concepts of DnD. Like any good GM, I never really wrote them down, but I've now decided to finally gather some of the better bossfights, and mechanics, and gather them in a Homebrewery Document. (yayyy!!!)
Here is the doc.
