SMT IV elemental weakness multiplier seems to be incorrect

[tireinny]

Currently, the elemental weakness multiplier is listed as 1.25x, but after several tests, I've noticed that I'm doing way more damage than I should given a 1.25x weakness multiplier.

With 412 magic against an enemy weak to ice and using Bufu, which has a base power of 80, I should be doing (412 * 1.5 + 80 / 3) * 1.25 damage, which is around 800 damage.

Instead, I'm doing around 1000 damage (subtracting the 24 damage bonus from +8 skill potential).

This suggests that the multiplier is around 1.55x, as (412 * 1.5 + 80 / 3) * 1.55 is 999—basically 1000.

How much damage does Agi deal to Dybbuk with the same setup?

Since I made the post, my magic increased to 424.

Damage ranged from the high 680s to the low 700s. It seemed to skew closer to 700 than it did to the high 680s, as I often got numbers in the high 690s, though it's possible this is just the result of good RNG. With 424 magic, the damage should be (424 * 1.5 + 80 / 3) + 24, which results in around 687 damage, which although slightly lower than what I usually obtained, I'd say it's still within expectation.

Weakness damage with 424 magic for comparison.

Once again, a 1.55x weakness multiplier continues to seemingly hold up, with 687 * 1.55 equalling around 1065 damage, very close to the numbers shown above. But that being said, I feel like the damage variance makes it hard to determine what the true multiplier is. 1.55x seems like the best-fitting one, but it might not be what the multiplier truly is. Knowing that likely requires data mining the game, which is outside my ability. But either way, this does definitively show that it's way higher than 1.25x.
