@ThisJagRawr: Mine was S rank pre-Unleashed, so it's Legendary now.

@ThisJagRawr He probably got it before the revamp. Special Circulators did not give out set values.

You can get that without having the Inner Ability lol. All you need is a Mechanic card.

The new inner ability system has set values per rank. 7% being rare, 19% for epic, 32% for unique.

I got 40% Buff Duration, which gives me permanent 100% Stance with Mihile Lv2 link.

@ThisJagRawr: I already know that, i also own a F/P Mage, i just said so because she stated bishop, so i wan't helping that much here.

I recommend Buff duration, it will still benefit a bit more than crit, IS JUST ME, you can take crit if you feel like you need to see more red numbers.

@ThisJagRawr edited my previous post to include possible Epic Adventurer and T&C
long story short, if you're going to have T&C and Epic Adventurer is affected by Inner Ability, just get whichever comes first.
the numbers above don't even factor buff times, which favor Buff Duration.
not to mention, Circs love to be whimsical (make you Unique for just 1 circ before dropping you down to Epic again)

Thanks guys (: just needed assurance. Now to farm more circs during bonus, lol.

15% Crit hands down.

@ThisJagRawr
let's see right now you said you have 53% Crit, with the normal 145%~150% crit.
current "crit multiplier" is thus 1.25175x (0.53*1.475+0.47)

with just 50% Buff Duration from Buff Mastery, Infinity is 1 minute long, buffing every 6 secs and I'll assume you get 10% starting after 6 secs (thus from 50s~60s you'll have +90%)
that makes Infinity 1.15x boost on average

15% additional crit makes your crit multiplier go from 1.25175 to 1.323, a 5.69% increase in dmg
if you're going to factor Phantom Lvl2 and Hyper, that's 68% crit to 83% crit, which is 1.323 to 1.39425, a 5.395% increase in dmg

32% Buff Duration from IA brings Buff Duration to 82%, making Infinity last 72.8 secs, buffing every 7.28 secs (not nice numbers...)
this brings Infinity boost from 1.15x to 1.182x, a 2.78% increase in dmg (surprised that multiplier came out nicer than I thought)

if we instead assume Infinity gives you 10% starting at 0 secs (thus 50s~60s is +100%)
60s Infinity to 72.8s Infinity is from 1.18333x to 1.222444x, a 3.305% increase in dmg

tldr; 15% Crit is better

oh, btw, Epic Adventurer seems to be affected by Buff Mastery but I'm unsure of IA's effects on it. if someone can confirm that it does:
90s Epic Adventurer is 10% boost 3/4 of the time, making it 1.075x boost on average overall. if you have Lvl2 DA AND Kanna this is 8.33% boost, thus only 1.0625x

Buff Duration would bring that to 109.2s, thus 1.075->1.091 = 1.488% and factored with Infinity, that's 4.8% boost at best (+100% at 50s~60s)
w/ DA and Kanna, that's 1.0625->1.0758333, 1.255% increase, a 4.6% increase at best

and now I remembered T&C...
well this is annoying to do since it's a smaller boost when both T&C and Epic are active since they stack additively... I'll simplify and assume one uses it right after casting Epic Adventurer even though T&C's cd is shorter than Epic's
the above numbers for EA are disregarded.
EA+T&C combo would be 1.13125 without DA + Kanna and 1.109375 with
32% Buff brings 1.13125->1.15925, a 2.475%, factored with Infinity, 5.3% at worst, 5.86% at best
w/ DA+Kanna, 1.109375->1.13271, a 2.1%, factored with Infinity, 4.94% at worst, 5.47% at best

tldr2; so many numbers...just get whichever you get first

[quote=IsGamer]With a 15% crit, we would had like 90%+ crit, but with our buff duration, we would get more benefits from infinity, trust me, any good replacements are sharp eyes, phantom link skill or a MM card (minot crit boost, but is something).[/quote]

I made this thread for archmage >.> not Bishops. I know buff duration benefits you guys more than % crit because of your guys high base crit %. I wasn't asking tho, I was inquiring for archmages since we have less % crit T.T

[quote=carbunion]I believe buff duration is additive, and would be better for infinity.

Which one is better I don't know - glad I don't have to make this choice as a bishop XD[/quote]

Yeah T.T Bishops and their high % crit. I'm at 53% crit w/ lv 1 Phantom link and 3% from MM card, so if I get Phantom link to lv 2, get to 198, and get 15% crit on inner, I'd be at 83% crit, but Idk whether to keep 32% duration for infinity or aim for 15% crit on inner.
