Ok, so assume the following. Capped Shellra V. Full barspell merits. A 1000 DMG Flare, no resists.

In my understanding, assuming the listed upgrades and gear, I should have reached the cap of -50% magic damage taken. 23.43%(240/1024 ???) from gear and 27.4%(?) from Shellra V.

At this point it's clear that the Flare should do 500 DMG to my char instead of the usual 1000. Here comes the tricky part. When does MDB calculate? At the same time M% or after. Maybe even before?

Let's say after first. 500 DMG base with 33MDB (assuming Barfira with max merits) comes to around a 335DMG blast.

If it's calculated at the same time, the reduction is roughly 83%, resulting in a 170DMG blast.

Calculating before, results in 333DMG.

Further reducing this damage with a /RDM sub for an additional 10MDB will result in a 280/70/280 DMG blast respectively.

The first obvious question is: which is the correct calculation? I can't test this myself since my PLD at the moment is just a toy, and I'm forced to go BRD to events (yay...)

The second question is, without taking Aegis into the calculations, which is the absolute best straight magic reduction set a PLD can get? Seems to me Resentment cape is situational for those odd times you don't have a capped Shellra V. Mind you, this isn't a resistance set, I still have long long ways to go with that one.

As always, I'd appreciate feedback from my fellow Paladins.

EDIT: Since I was curious, I found out what the best possible -dmg set there is available, and since I'm pretty sure I don't know how to calculate it, any math gurus please help me! Comes out to this:

Aegis + Shellra V = -50%magic dmg. cap.

Lamian Kaman +1 (+2 MDB)

Full IR gear + Ataractic Solea (+ 18 MDB)

Static Earring (+2 MDB)

Shadow Ring (Darksday +10MDB)

Volunteer's Ring (+3 MDB)

Resolute Belt (+2 MDB)

Lamia Mantle +1 (+4 MDB)

/WHM (+12 MDB)

Diabolos buff (+10?MDB)

Full merit Barspell (+10 MDB)

Comes to: MDB +73

Also, assuming Magus' Roll with a BLU in party is MDB instead of -DMG taken (I tried looking for it and couldn't find a definite answer). Gives +33 on XI with BLU in party. If it is indeed MDB, total comes to +106MDB.

So, -50% magic damage taken AND 106%MDB. How does it calculate? Seems to me only mobs with Magic Attack Bonus can hurt you this way, unless it caps at some point.
