does immunity overrule vulnerability, or the other way around?


Rules Questions


When doing a build to update an old school adventure I created a Fire Giant Mummy Lord. It has Vulnerability to cold and Immunity to cold. Which is in play?


Read the section about creating undead and the undead traits. From memory I am fairly certain that the undead creature loses all of their abilities the original creature had in life.

Immunity says "reduce all damage from <thing> to 0"; vulnerability says "multiply all damage from <thing> by 1.5".

If you apply vulnerability first, damage is multiplied by 1.5 and then reduced to 0. If you apply immunity first, damage is reduced to 0 and then multipled by 1.5, which is still 0. Either way, the target laughs at you.

that entirly depends on the type of undead there are only a small handful of undead that lose their normal stuff, most undead keep what they had while they were alive for abilities


also mummy lords dont get the normal mummy's vulnerability to fire

I cannot find anything in the Acquired Template for Mummy lord nor the undead traits that suggest the natural abilities of the fire giant in life are lost in udeath (unlike mindless undead).

Yeah, it's an interesting way to stack things.

I made a Red Dragon Lich along the same lines. The pile of immunities became impressive.

Heck, why not both? Give the sucker some class levels while we're at it :D

Sadly, you cannot. Both template can be applied to "any living creature."

Regardless of which template you apply first, it turns the creature Undead, and thus not a legal target for the other template.

As a DM, you could do whatever you want, but normally the templates cannot be combined.

Regardless of the legality in doing so, I understand immunity to trump vulnerability.
