As far as we know, mobs don't have any sort of defense or resists. That's why ladybugs and Savage mobs take the same damage from the same attacks, and why BLM isn't useless against Ifrit or Shiva. But, this situation gets more and more fun!

Katon: 782-865
Aeolian: 784-867 (uncombo'd, rear attack)
Both 180 potency.

Doton: 135-150
Mutilate: 135-150
Both 30 potency.

Fuma: 1046-1157
Aeolian: 1046-1157 (combo'd, flank attack)
Both 240 potency.

So Fuma is accurately 240 potency. Doton is probably accurately 30 potency (or the error is too small to observe). Hyoton and Katon are demonstrably not their listed potencies, and Raiton is probably not though has no matching-potency WS or ability to test against. Most interestingly, Doton is unaffected by Foe Requiem, and I didn't see any effect from any of the resistance-down debuffs.
