I just came across this. It’s an awesome, extended version of The Game Master’s Apprentice Deck, which is an oracle deck which is excellent for solo and group TTRPG.

This online version, however, has lots of extra features. Look at the buttons across the middle (it’s easy to miss that they are buttons) that let you randomize NPCs, dungeon rooms, encounters, etc.

I found this really helpful. I hope you do too.
