@squeedgeWould a dragon’s breath weapon be considered a magical effect for the purposes of Antimagic Field? don't think so. I've always thought of it as natural phenomenon

@mikemearlsProblem I’ve had w/that kind of thing is if shadow dragon breathes on humanoid and undead shadow rises, that’s totally natural? And then, where is the line drawn? I always thought of dragons as magical cause they are described as magical creatures in MM

@squeedge I would put the shadow dragon's breath down as magical, and it's cool to rule it how you wish in your campaign
