How does weaknesses and resistances interact with critical damage?


Rules Discussion


Hey guys.

The thread is pretty self-explanatory. I'd like to know if weaknesses and resistances are applied before or after doubling the damage in a critical hit. Also, a formula for calculating bonus damage would be welcome.

Thank you!

From the rules on damage here, doubling damage on a crit (or halving damage on a successful save for many damage spells) is part of step 1, while applying weakness and resistance is part of step 3.

So weakness and resistance come after and don't interact with critical hits.


Well oof. Looks like I accidentally misled my group on a fight, then.

So, I double everything (except deadly die damage) and then I apply any weakness/resistance?

Yes. Just follow the steps. Weakness is not doubled if that is what you what you wondering about.

Got it. I assume die bonus damage (such as frost and flaming weapons or weapons with the deadly trait) are applied in step 4 and also not doubled. Correct?

If the extra dice are only added on a critical, like from Deadly, they don't double. If the extra duce show up on a hit, like flaming weapons or sneak attack, they do double.
