I think I remember starting reading their campaign notes at some point, but I didn’t finish them! Thanks for reminding me!

Reminds me of the time when my Ulfen human Skald in the Pathfinder Giantslayer campaign died and was reincarnated by the party druid as an ysoki - more commonly known as “ratfolk”.

This was not something he expected, but he reasoned: “I have never been ashamed of who I am for a single day in my life, and I am not going to start now!”, and thus he rolled with it and stayed in that form for the rest of the campaign.

An addendum: I just discovered the SRD for Level Up: Advanced 5E by EN Publishing. And the document for NPCs does have simplified stat blocks which include spell descriptions for many NPCs!
