A player's PC received an enchanted mace, a +1 weapon with the ability to shine like a torch.
(Lightbringer from Lost Mine of Phandelver for those familiar.)
Does this mace deal magical damage for the purpose of overcoming resistances?
Nothing like that is mentioned in the stats; but another player argued that a weapon that's magic should be a "magical weapon". I disagree as I like to follow the books, and they seem to be pretty specific about this kind of thing, but I wanted to ask people with more experience.
