DT; MDT ; MDB

So with a monster having 300 MAB, you 0 MDB and nuking you for 2000 damage... now adding 100 MDB and taking 1000 damage (which is 50% reduction) is not in fact 50%?

Rule 1 of determine the effects 1 a variable... don't change other variables. This whole comparing increases in mab to mdb to determine what mdb doesn't work simply because of that.

And I know it isn't explicitly being stated as changing but that's what you are doing when you actually plug it into the formula as you are effectively comparing it to a change from 1. Same as if you plugged in any of the other multipliers. Would be like saying mdt only works half as much if mob has +100 mab which is silly unless you really meant to say something much more like you'd take the same dmg as you would've with a mob without mab with half as much mdt (keeping all other variables the same)

Mob MAB does not skew the results because they're independant variables, and thus do not effect each other. The amount of MAB a mob has has absolutely zero effect on the percentage decrease in damage MDB grants you. Changing the MDB term from 1 (100/100 MDEF) to 0.5 (100/200 MDEF) reduces damage taken by half no matter if the MAB term is 1, 10, or 100.

Actually compare 0 MDB and 100 MDB situations in the formula and you'll find that the amount of MAB you choose doesn't affect the percentage difference at all, as is required by the rules of arithmetic.

Troll dealt with.

This discussion happens every few months and there are always people who try to claim that the value of caster MAB and target MDB are somehow related to each other.

A total of +100 MDB will always cut your magic damage taken in half, no matter how much MAB the caster has.

A total of +100 MAB will always double the damage of your spell, no matter how much MDB the target has.

Mr. "Click, problem solved!" strikes again.

No it won't. Doubling your MDEF will cut the magic you take in half, going from 0 to 100 MDB just happens to double the 100 MDEF you start with. Idiots like to pretend we're still at 75. Same goes for Magic Attack.

50 MAB, 50 MDB

150/150 = 1.0

+100 MDB
150/250 = 0.6

+150 MDB
150/300 = 0.5

I keep hammering this because we don't start with 0 MDB anymore, iLevel and gifts have changed our starting MDB. Barspells and a few other buffs / vorseals / ect.. can further add to MDEF. In an extreme example, a Master RUN starts out with 78 MDB for a MDEF of 178. It would talk another 178 MDEF to "reduce the magic damage by 50%". We don't go around saying dumb ***like "adding 100 defense reduces the damage you take by half" even though it would, if you only had 100 defense. The exact reduction of any amount of MDB would depend on how much MATK and MDEF was already present.



I have it on very good authority that person was deliberately trying to troll me and brag to their friends about it. Best way to deal with trolls is to ignore them permanently.

No one was saying arbitrarily adding 100 MDB to any number. The original claim was that MDT reduces what you gain from MDB. Which was wrong. And then some numbers were shown to show why.

Then you came in saying things like high MAB skews results. Which is also wrong.

We are explicitly talking about being at +100 MDB from neutral.

Yes, RUN has +78 MDB (50 gift, 22 trait). We are not talking about adding 100 to that. It would be adding 22 to that to make 100.

But even then with your example of RUN, if it remains unchanged at 78 MDB (e.g. not adding through gear, lost through malaise, etc.) it will always reduce damage by ~44% compared to a character with 0 MDB. Whether the enemy has 0 MAB, 175 MAB, or 10,000 MDB.

Not sure how you don't understand this.

It's Saveal. Once he's typed something the best you can hope for is the small back pedal he's already done

Ask him about his thoughts on the "May 10th summoner nerfs".

sorry for the necro bump. but pld emp gear has 5% absorb rate on both magical and physical damage when wearing all 5 pieces right? does the other 5% from say warder's necklace +1 or tarutaru platemail stack with this to make magic 10% chance?

Some pieces of "absorb XXX damage" do stack while other do not. Here's some of the testing that I did a while back:

https://www.ffxiah.com/forum/topic/46016/first-and-final-line-of-defense-v20/137/#3682264

The big ones that don't stack together:
1) Warder's Charm, Engulfer Cape, and Tartarus Platemail.
2) WKR capes and Abyssea Satchets (maybe Zanhi Ring too?).

okay i checked the link out, but it didnt answer my question. ill do some testing and find out! ^ ^

edit: upon scrolling further down and reading i found your test lol im sorry for that!
