"Wait, that didn't work right" - the Dysfunctional Rules Collection

Where does it say that Necropolitans are healed by positive energy? Even by RAW, I think they are hurt by spells like CLW, since their type changes to undead.

They may be referencing the fact that Undead are technically healed by the positive energy plane, because it doesn't do positive energy damage, it just gives fast healing 5.
