Paladins get the Divine Health feature at level 3:
By 3rd level, the divine magic flowing through you makes you immune to disease.
If a were-animal bites a paladin of level 3 or higher, would they be immune to turning into a lycanthrope themselves? I know people say lycanthropy is a curse, but is it also considered a disease?
Best Answer
Paladins aren't immune, because lycanthropy isn't a disease.
Lycanthropes and lycanthropy are described in the Monster Manual (p. 206):
The description continues in much the same way. As you can see, lycanthropy is repeatedly described as a "curse", not as a "disease". As such, the paladin's Divine Health feature provides no protection against it.
