Hi again guys. Been with roll20 since 2012 I bought a 3rd party module for use here and it had me thinking, do I need to get the PHB, DMG, and MM as well for it to be seamless? I've never used paid content on roll20 till now and will get it if need be but didn't want to waste money if that makes sense. As always, your help is appreciated. if it matters the 3rd party content is Crown of the Oathbreaker. It was pricey but looks nice. That bundle is full of stuff.
