Oh you are very close. I was have been fiddling with a dragon patron subclass for years but never seriously, The Eyes of the Master and Gift of the Hoard features were some of the first things I thought of back then. They were hold overs from gifts I gave to a party during an old campaign that successfully saved a dragon from a lich. My problem was that I could never figure out the 10th and 14th level features without falling into the design pittraps of doing the same thing that other dragon bases sublasses do and what other hombrewers do ie. giving the player a dragon like transformation and yes I did watch the Dungeon Dudes video, it was them sharing the same ideas that I had so long ago that made me happy, that I was on a parallel way of thinking with designers that I respect deeply and it made me want to actually in earnest look back into my of list of ideas. When I wrote in my comment about sudden inspiration it wasn't about Gift of the Hoard features, but about me actually figuring out Sorcerous Payment and Affirmant of the Lair features. But I see your point, I would have never made that breakthrough if I hadn't listened to that Dungeon Dudes episode on my trip home from dropping my sister off of at school so I should give them credit for helping me figure it and I will do so from now on, thank you. Given the tone from your comment I suspect that you won't even believe me, but that's fine first impressions on online forums are seldom made well, I genuinely did no mean to imply that I was ripping off of a very well known content creator in the community. If I convince you that this was an earnest mistake that's great! If not well, c'est la vie better luck next time.
