Thanks so much for sharing! This is really helpful for me to hear—I'm actively working on updates and revisions while running my own campaign right now.
If you have a moment to field a follow-up question: When you say almost everything they've fought has been owl-bear-ish, have those been lone owl bears? (Still trying to figure out how many HP is okay to make sure fights don't drag. 20 seems to be just about the upper end for a solo for my group, but the "d4 [number appearing]" on the Knave 2e owl bear made me think to ask!)
