Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

Playing a divinate paladin. I noticed that the Divine Health on the paladin does not prevent him from getting diseased by disease cloud mobs like the ones found in gullykin crypt or the field of dead crypt.

My monk doesn't have this issue.

Is this by design or a bug?

Thanks.

Working as intended, that is not a disease.

That particular cloud is, if I remember correctly, actually a poison.
