Multiple vulnerabilities

[keterys]

A target has vulnerable 10 radiant and vulnerable 5 all, and is hit by a radiant sunstrike for 7 radiant. How much damage does it take, 17 or 22? Rules or FAQ or CS citation?

Potentially more complex. A creature has vulnerable 5 thunder and vulnerable 5 lightning and vulnerable 5 cold and is hit by a power that deals 7 thunder and lightning and cold damage. Same questions.

Much appreciated.

The answer is essentially stack up the damage (so 22) from Customer Service: 4E Customer Service Answers - ENWiki

Hmm, I wish there was an answer since they combined damage types so they weren't separate and something more official. But thank you very much

Well, I guess you have to assume that a CS person provided that answer before someone put it on the EW wiki, but you did ask for a CS answer as one option!

Did this change in an errata? I was aware that the greatest vulnerability/resistance was applied, that is, they don't stack. I would think that makes more sense since "vulnerable all" encompasses "vulnerable radiant", only the greater of the radiant damage vulnerabilities is used (in this case, 10).

Oh, definitely. I meant it more that combined energy damage (ex: lightning and thunder) used to split it up, go against both resistances, etc. But now it's combined. So the answer would have been more useful if it had been post-that-errata

That does seem like a common sense interpretation, but I haven't seen anything to suggest that it is true. I'd very much like to know if it is true anywhere... so if you have a rules citation, any at all, it would be appreciated.

There is this in the PHB FAQ:

30. Do resistances stack?

You use your highest applicable resistance when you take damage. For instance, if you have both resist 5 fire and resist 1 to all damage, you have resist 5 against fire damage and resist 1 against all other damage. You do not have resist 6 against fire damage.


While this speaks to resistances it would be more consistent if vulnerabilities worked the same. So for your original question, I'd say 17 damage.

Weirdly enough, resistances are not the same as vulnerabilities. For instance, even aside from this -- if you're hit with "fire and lightning" damage, it will blow straight through fire resistance; you need fire resistance -and- lightning resistance to avoid it, and only the lowest will apply. By contrast, fire -vulnerability- will happily increase the damage; you favor the attack. Similarly, yes, you use the highest vulnerability in a category, but stack all the categories. If someone is vulnerable fire (5), all (5) and psychic (5), they'll take +15 points from fire,psychic damage. But if they're vulnerable all (5) and all(10), they only take +10 damage, not +15.

This is somewhat offtopic; but is it just me or do these links redirect to the logout page?
