I was wondering what books it would be smart to get to try and follow what classes they play, abilities, monsters ect and if anyone has a link to a place to buy them if linking like that is okey by on here?
Here are amazon links but You can probably find it in other online retailers and your local game/comic book store
Other than the two listed above Adam also uses the Monster Manual for monsters, see below:
To add to Noor’s post, if you’re unsure about Volo’s Guide and you’re a patreon, Adam and JP created a rollplay review on the book.
