Elemental Obis

[Alastaire]

Noob question, I've just never known: Do elemental obis only increase potency, or accuracy as well? And do they count for non-nuking spells.

[Lylie]

I would say no and no. Obis only increase your nuking damage by 10~20~30% depending on Day~Weather.

[Xfaustx]

I would say no and no. Obis only increase your nuking damage by 10~20~30% depending on Day~Weather.

yes its 10% for each thing. day = 10% weatherx1 = another 10% and weatherx2 = 20%.

when he said potency i think he means MAB.

[Jer]

I think he meant no to the accuracy and no to the non-nuking spells. OP knows it does potency

[Suiram]

If the day or weather condition has a random accuracy bonus, then the obi should make it constant, same as potency bonus. As for whether or not such a bonus exists, I've never seen any tests one way or the other but it sure feels that way, right?

Also just for the record, for potency, day = 10%, single weather = 10%, double weather = 25% (max with all three is 35%) and it's technically not MAB either but you get the idea.

[aurik]

There's really well documented research on obi damage bonus on Wiki.

As for accuracy bonus, I think there is but there's very little evidence either way due to the difficulty of generating that evidence. If there exists a day-bonus to magic accuracy, then the obis SHOULD guarantee it.

[Alastaire]

I was always under the impression that a specific day gave an accuracy bonus to element-specific spells, which is why I'd wondered if the obis would enhance that or whatnot. In any case, thanks for the info.

no, he means potency.

Magic Potency =/= Magic Attack Bonus

[Xfaustx]

when you say potency you are talking about the effect of a debuff or said enfeeble correct? where as MAB is a %+ based off the damage of your INT. i thought the obis did MAB. thats all i hear anyone say is its 10 MAB per effect, never heard anything about potency.

I know that ice weather definitly seems to affect sneak/invis spell potency (see uleguearnd range). So it would be safe to assume that there is at lesat some accuracy bonus for the corresponding spell in weather, and probably day as well.

[Nerull]

Potency, with regards to magic damage, is typically used in a general sense to mean something that multiplies your damage by a percent. For example, a HQ staff adds 15% potency, i.e. multiplies your damage by 1.15. Casting a Thunder spell on Lightningday, with a Rairin Obi equipped, adds 10% potency, i.e. multiplies your damage by 1.1.
These things have nothing to do with Magic Attack Bonus. It is an entirely seperate multiplier. When you equip Zenith Mitts, MAB+5, this does not multiply your damage by 1.05. What it does, is adds 0.05 to your current MAB multiplier. A 75 BLM with the job trait MAB IV, has an inherent MAB multiplier of 1.32. Zenith Mitts increase that to 1.37.

Understand the difference? Just simple math here. Yes I know I'm OCD.

For a more thorough explanation of exactly how magic damage is calculated, the wiki article is pretty good.

[Kaylia]

-ga spells with 2 through 9 targets = 0.9 - 0.05T where T is the number of targets
-ga spells with 10 or more targets = 0.4

Damn. I always thought there was no limit to that. Is it the same for HNM like AV/kirin/behemoth?


Any idea how blm's potency are calculated? Is it added to the multiplier with the staves? Before/after?

[edit]

nvm, merit are +2m.atk. I thought description said 2% dmg potency

[Suiram]

Oh, the merits are +2 per merit to MAB. So if you have 5/5 Thunder Merit, it's equivalent to wearing a piece of equipment that says, "Casting Thunder Spells: Magic Attack Bonus +10". MAB itself is totalled up and then multiplied to your damage after staves, day, weather, and MB. So really it's not a 10% increase, it's at most a 7.5% increase if you're not wearing any gear, less so after you factor in MAB from gear.

Edit: Nvm, looks like you answered your own question lol

[Kaylia]

Yeah, I just misunderstood the nature of the potency bonus on merit

Lightning Magic Potency (+2 potency per upgrade)

Their description is kinda confusing imo. Should just say +2atk like they did for Ancient II spell. I hate when they play around definition and use different term for the same thing.



While I'm at it, what does "Burst II (+3 Magic Burst Damage and +5 Magic Accuracy per upgrade) " mean

5m.acc all the time and 3m.atk on magic burst
or 5m.acc/3m.atk on magic burst only.

[Suiram]

That's difficult to judge, because unlike testing magic damage, where after picking the appropriate conditions and test subject the answer lies in the only valid conclusion you can draw from your results, testing magic accuracy is statistics, like claims about treasure hunter and crafting are subject to people's preconceptions and superstitions, unless someone wants to go out and nuke the same somewhat difficult mob hundreds of times with level 1 and level 3 or whatever it is you are trying to test about accuracy and resists.

That said, I personally am inclined to say the magic accuracy is "always on", just because that's how I interpret the wording of the description in the merit menu.

[Kaylia]

Yeah, I don't think it's possible to test 5m.acc like this. That's also how I interpret the wording, but SE always make me doubt what I read.

Any idea what jp version says, they are usually more accurate

[Alvinho]

I was under the impression that Obis don't add anything at all. What they do is make sure you get the day/weather bonus when casting a spell on the corresponding day and/or during corresponding weather.

In other words, you could do the same damage you would do with the Obi equipped, without the Obi equipped (if you are lucky).

Also, if if you have Hyorin Obi equipped, on Iceday, and cast Aero IV, you will get the full day penalty (or day ‘‘bonus’’).

[Xfaustx]

Nerull you managed to confuse me even more than i had been before... i always thought MAB was a % of damage. like MAB+15 was 15% to your damage. but now your saying its not. everything ive grown to know and love about BLM is being thrown into shambles. what gear actually states +? potency on it. i need a light to shine me in the right direction.
