One word I wouldn't use to describe the book would be "consistent".

You're art style is so distinctive it's amazing 😍

The ever growing list of adventures to write haha

Hmmm maybe it's a local village ritual that their ancestors always did but this year it actually works. If you could pull it off it'd be a great kick off to a campaign

The first couple of quests could be the party collecting items that end up being used in the ritual. Black goat, broken horn, amulet that kind of thing. This might be a full baked idea haha

His statblock is so bad I'd actually give a level 11 Paladin with the sunsword a very good chance to solo him

In a perfect world it means that it is compatible with older content and it's balanced with older content.
My expectation is that it will "work" with older content but the power level of new content will step everything up, making old content feel obsolete.

If there exists a Goodberry what about the Badberry

Roll for shoes ! 6 rules and you only need D6's

If you distill playing a TTRPG down to a single click of a button and the AI tells you what happens, you're not playing a TTRPG.

It also sounds like you are trying to call the gods of breakfast !

Coldest it got in my area was -6°c and it was damn cold ! Stay warm and safe

If bonus actions were just a swift action to let you turn on rage or use sneak attack/smite then it would be fine but it is out of hand for some classes. I'd love to see some revised classes without them

Does Santa play elves and Artifacts ? Or maybe something from Eldraine ?

I'm exactly the same, I wanted it to fulfill that tinkering fantasy but really the best artificer is a wizard at this point, I think.

If the campaign has an end, that's railroading.
