Given the estimated base damage and level correction, we can determine that capped Ratio is 2.0. 3.1 * 188 = 582, and capped damage on the triple attack round is 1743/3 = 581 (so probably some missing rounding in there). Therefore the minimum defense necessary to have any effect whatsoever is 530.

An interesting consideration: Would you rather have Gallant's + Dia III, or Chaos + Bio III? Assuming that either the increased defense or lowered attack is necessary to survive the fight, while the other buff/debuff is to improve damage done.

One would then want to compare the value of Gallant's Roll with Bio III. -15% att from Bio III would put Ig-Alima's attack at 900 instead of 1059. Minimum useful defense is 450. Using the BCB defense values:

Def 1: 460 (baseline)
Def 2: 575 (Defender)
Def 3: 663 (Defender+food)
Def 4: 821 (Defender+Gallant's+food)
Def 5: 345 (Berserk)

Default triple attack round

Def 1: 1743
Def 2: 1659
Def 3: 1521
Def 4: 1361
Def 5: 1743

Reduce that to a single hit value

Def 1: 581
Def 2: 553
Def 3: 507
Def 4: 454
Def 5: 581

And look at the results for various defenses to see how it compares.

Def 1: 575
Def 2: 501
Def 3: 462
Def 4: 413
Def 5: 581

We see that Bio III isn't quite as effective as Gallant's Roll, resulting in 462 damage taken instead of 454 without adding Gallant's. Still, it's quite close.

A 30% attack boost (from 900 to 1170, Chaos Roll 11 without drk bonus; assuming 600 defense) would double an attacker's damage (cRatio going from 0.45 to 0.9). Dia III in those same circumstances would increase damage by 59% (0.45 to 0.715).

So in the overall combination of those effects, Bio III + Chaos is better than Dia III + Gallant's.


Let's also take another look at the value of Chaos Roll for a pld. While it's usually considered the better option for hate, if the pld is turtled up it may actually not even have any effect at all.

Assuming that same 600 defense, an attacker would need an attack of at least 630 just to get above a 0.0 cRatio. If the pld is using defense food and Defender (-25% att), and then given a +30% Chaos Roll (net +5% attack), they'd need at least 600 attack just in gear to get above the cRatio floor, and that is highly unlikely. They'll probably be lucky to have better than 500 attack before buffs. Even if you add a Stalwart's Drink to that, that will still only barely move you above the 0.0 floor (650 attack total vs the 630 needed).

So in that sense, yes, there's no value in giving an attack buff to the pld, while a defense buff would at least do -something-.


So if we're going to turtle up, might as well do a proper job of it. Going with a generally high-def gear set, plus Proctect V, for 650 base defense. We can actually broach 1000 defense with that, but since that depends on an 11 from Gallant's Roll, I'm still going with Tacos. Since you lose a point of def from 4 vit instead of 6 for BCBs vs Tacos, Tacos still end up 1 point ahead anyway.


Def 1: 650 (baseline)
Def 2: 812 (Defender)
Def 3: 966 (Defender+food)
Def 4: 1160 (Defender+Gallant+food)
Def 5: 487 (Berserk)

Damage taken for single-hit:
Def 1: 513
Def 2: 452
Def 3: 413
Def 4: 378
Def 5: 581

Fully turtled up results in a 32% reduction of damage compared to using Berserk. Adding Gallant's Roll to Defender+Food reduces damage from 413 to 378 -- 35 damage, 6% of Berserked defense, 6.8% of nominal defense, or 8.5% of Defender+Food.

So, depending on how you measure it, Gallant's Roll is worth 1-2 middling to good Dark Rings.


Now compare that to the best possible Chaos Roll bonus. 40% attack with drk bonus. Given somewhere in the neighborhood of 600 attack before food (closer to 700 for a drk), 40% attack is worth a good 240 attack. I cannot think of any gear that would give you anything remotely close to that much attack in just 1 or 2 gear slots.

One could argue for the actual numeric defense increase, which is 194 in this case. Creed body+legs is 135 defense, but it would be difficult to get another 60 def in one more slot. However since Creed legs also gives you 5% PDT, it already surpasses the value of Gallant's Roll.


Overall, in any sort of comparison of worth -- point-for-point reduction, buff trade-off, equivalent debuffs, gear equivalence, etc. -- Gallant's Roll fails miserably. That doesn't even get into the value of defense as a stat in the first place.

If you want to even pretend that this roll has any value whatsoever you'd need to practically double its defense increase (ie: +60% defense on an 11 with pld). At 20%-30% (and even that's on an 11; average will be a fair bit lower), it's an absolute joke.
