I hesitate to ask this here...but why not?

So there are two forms of virus: one that can be improved via arcanist traits and the other that can be cross classed. One of these works on four stats and the other only on two.

As a BLM main, I have tested quite a few of my abilities in certain situations to determine if they are magic-based or physical-based. Manawall tells you if it's physically based and manaward tells you if it's magic-based.

With the 'nerf' to virus via antibody and no distinction between either, this has been bugging me for quite a while:

Which mob attacks are modified by strength? By dexterity? By intelligent? By mind?

Let's use a simple case: Titan HM.

Landslide, for instance, is considered physical damage. Mountain buster is also considered physical damage. Both are negated by manawall.

Does this mean that landslide and mountain buster are modified by the strength attribute of the mob?

Next, bombs and tumult are magic-based damage. Manaward negates a fraction of both.

What, then, is the primary stat of the mob (Titan, in this case) that modifies his tumults? Is it intelligence? Is it still strength?

I ask this because it is a common thing to throw up virus on Titan before he uses his MB > tumult combo. However, if, say, a BLM were to throw up virus over a SCH or SMN's virus, this would only work on the MB damage (assuming it is STR-based) and do nothing for the tumult damage, correct?

Or is my understanding of this nerf different. If a non-SMN/SCH uses virus and the mob receives the STR and DEX down debuff, will he also receive an INT and MND debuff if a SCH or SMN casts it after? Or will it have no effect at all?

On things like Twintania where you are worried about warding against death sentence damage, it really isn't an issue because it appears that STR modifies death sentence. However, on things like aetheric profusion, it would appear people prefer the SCH or SMN to virus Twintania for a perceived decrease in damage due to aetheric profusion possibly being modified by INT.

If it turns out that it's more efficient to let SMNs and SCHs handle virus because of four stat debuffs, I would like to know. While I do main BLM, SCH is my secondary so it'd be beneficial to know whether to tell others to let myself/the SMN handle virus or not.
