Realms of Solo

Realms of Solo
Solo Roleplaying Realms of PerilRealms of Peril by Spellsword is an interesting mix of Powered by the Apocalypse and d20. You get all the PbtA features you know and expect, player-facing rolls and moves for everything, but all scaled up to use a d20.
The other cool thing about the core game is the wealth of random tables in the Game Master's Reference. There is nothing that makes solo play easier than having random tables for everything that is perfectly in tune with the game's feel, genre, and setting.
Against this background the solo rules in this booklet use a d20 oracle based on the basic move, and d20 oracles for when you need something that is not covered by the GM Reference.
On top of that you get my normal advice on improvisational play, soloing, and some of my hints and tips that have grown out of my experience.
