Did some Leaden Salute testing with various MAB/Magic Damage values and learned something interesting about Archon Ring that I haven't seen anywhere. I don't think this was already known, apologies if it was.
It seems that 'Dark Elemental "Magic Atk. Bonus"+5' isn't added to MAB normally but is actually a different multiplicative term, at least for magic WS.
That is, rather than
Code:
((fLvl + fILvl + WSC) * fTP + dStat + mDmg) * MAB
it looks like the formula is
Code:
((fLvl + fILvl + WSC) * fTP + dStat + mDmg) * eMAB(element-specific) * MAB
I tested various combinations of AGI/MAB/MagD values with and without Archon Ring to confirm:
Code:
Job: COR/SAM
Target: Wild Rabbit
Weapon: Pulfanxa (except last test, Death Penalty for that one)
No MAB sources (except gear), no weather/day bonuses

Pred is the predicted value from the original formula
Actual is the damage the weaponskill actually did in the field
Mod is the predicted value using the modified MAB formula
Also checked the flooring order, MAB(Elemental) is definitely applied and the result floored before MAB is:
Code:
=FLOOR(FLOOR(((fLvl + fILvl + WSC) * fTP + dStat + mDmg) * MAB(Elemental)) * MAB)
Didn't test with staff/day/weather bonuses, but without them that flooring order gives exactly the right results in all cases (and reversing the order gave the wrong result in some cases).
I would guess that the same is true of other "Element: MAB+" gear, such as Ngqoqwanb, Chimera Hairpin, Kaikias' Cape, Ossa Grip, etc. but I haven't tested any of them (no Chimera Hairpins available and the rest of the gear is all for jobs I don't have). Would also expect it to apply to other MAB-affected abilities and magic.
