Hello there,

Second time that I post here, first time was for a fan art.
I hope that this post will help most of you.

So, what if I told you there is a BiS Tidus, without enhancement, that use Fixed Dice (as some of you hate RNGesus, I won't say that it's BiS, so I name it near BiS)?

I’m not kidding.
I made some maths and saw that even if I loose a turn with Jecht Shot (without Chain, it’s like a lost turn) in order to get the water element on Tidus, I do really similar damages over 5 turns than a « BiS » Tidus with Save The Queen, Brotherhood and Genji Glove.

(One these BiS builds, I didn’t put limited time stuff like D. Rain TM)

So, here are the builds :

So, yes. I know, the attack is squared in damage formula, so, 966 - 112|135 = 854|831. Like 25% ATT more for each weapon than Fixed Dice one. Squared, it’s like 56% damage more.

However, Fixed Dice damages, averaged give you 285% more damage (3,85x).

Not convinced ?
Well, let’s do a simulation.

Best scenario for double Tidus with Fixed Dice is this one :  
    T1 : Jecht Shot,
    T2 : Blitz Ace (LB),
    T3 to T5 : Quick Hit. Then repeat again.

For double Tidus with Genji Build, it’s :  
    T1 : Blitz Ace,  
    T2 to T5 : Quick Hit. Repeat again.

Don’t forget that Fixed Dice take full profit of Blitz Ace damages unlike DW builds...

Let’s do some calculation :

We will start with the easy calculation -> Jecht Shot.

Tidus 1 : 100% x 400% = 400%  
Tidus 2 : 110% (chain, no water element yet on the weapon) x 400% = 440%   

Blitz Ace, among its 16 hits, seems to have 14 that chains and break, then break again.

So, that’s like 410% for the first one (and 820% for the second Tidus thanks to the imperil).

Tidus 1 : (100%   160%   220%   280%   340%   400% x 9   100%   100%) / 16 = 306,25%  
Tidus 2 : (130%   190%   250%   310%   370%   400% x 9   130%   130%) / 16 x2 = 638,75% (x2 cause the water debuff is up)

So, with imperil and LB modifier, it’s :
Tidus 1 : 306,25% x 410% = 1255,625%
Tidus 2 : 319,375% x 410% x 2 = 2618,875%

Now, it’s time to do Quick Hit.

We will see admit that DW can perfect chain easily.

Fixed Dice or for the first weapon on DW (as the second wave has a x4 chain bonus) :  
    Tidus 1 : (100%   160%   220%   280%   340%   400% x 7) / 12 = 325%  
    Tidus 2 : (130%   190%   250%   310%   370%   400% x 7) / 12 = 337,5%

So, with that average damages, we can calculate some effective modifier :  
    Tidus 1 : 325% x 400% x 2 = 2600%  
    Tidus 2 : 337,5% x 400% x 2 = 2700%

For the first strike of DW, as spark is mandatory (need to know if elementary spark is  50% or  70%) :  
    Tidus 1 : (100%   200%   300%   400% x 9) / 12 = 350%  
    Tidus 2 : (150%   250%   350%   400% x 9) / 12 = 362,5%

Here again, with that average damages, we can calculate some effective modifier :  
    Tidus 1 : 350% x 400% x 2 = 2800%  
    Tidus 2 : 362,5% x 400% x 2 = 2900%

The second weapon has 3200% (400% x 400% x 2).

Now, we have for Fixed Dice :  
    T1 : 840%,  
    T2 : 3874,5%,  
    T3 to T5 : 5300%

(840%   3874,5%   5300% x 3) x 3,85 x ATK^2 = 20614,5% x 3,85 x ATK^2 = 79365,825% x ATK^2

DMG = 79365,825% x 675^2 = 361 610 540 (against an enemy with only 1 on DEF of course, and that's over 5 turns)


With DW :
    T1 : 3874,5% of the first weapon,  
    T2 to T5 : 5300% of the first weapon again and 6400% of the second one.  
(3874,5%   5700% x 4) x ATK1^2   6400% x 4 x ATK2^2 = 26674,5% x ATK1^2   25600% x ATK2^2

DMG = 25074,5% x 831^2   25600% x 854^2 = 370 908 589 over 5 turns

Now, let's compare turn by turn damage difference (cumulated) :

I know, Fixed Dice is still a bit worse, but just for 2,5% (and if you luckily spark chain, Fixed Dice will do more damage).
However, if that’s the way to do easy chain without macro, I’m okay with that.

Pro of this build :

• It allows Tidus to reach 70% evasion!
  
• 4 to 5 frames of forgiveness for perfect chain versus 0. Even if you're late of 9/10 frames, you won't loose too much damage.
  
• You can spam LB's for MP management, you won't loose that much damage (once debuff hit, each turn, it's like 5130,125% for LB vs. 5300% for Quick Hit).
  
• You can do better damages than DW build if you spark chain.
  

The cons :

• Too much RNG, so you could have a blowing 6,5x variance on Jecht Shot and 1,2x on Quick Hit. On long fight, it should averages to 3,85x.
  
• The goal is to not rely on spark chain, so it's 2,5% less damage over 5 turns.
  
• The fight has to last at least 4 turns if you don't want to loose too much damage (and that's only with an averaged RNG)
  
• More players have to know this build in order to not kick you from their FL as your Tidus seems to be weak.
  
• Tidus dies, he have to do Jecht Shot again. That's one more lost turn.
  

By the way, if you look at the percentage, you can see that damage modifier from weapon 1 to weapon 2 are really near while Dual Wielding. So if you can't do perfect chain, put your best weapon on your right hand. You won't loose that much damage if you achieve a perfect chain.

Thanks for your attention.
And sorry, english is not my native tongue... I tried my best to be as straightforward as possible.

Edit : I realised that DW needed spark chain in order to do the perfect chain. That change a bit the calculation. So, in the case you spark chain DW and not FD, DW is better damage wise while difficult to achieve macro. However, if you can spark chain FD too, this build is better.

Edit 2 : I'm still farming Brave Suit, I'm missing this part for this build, but you can add me if you wanna try the build with an another Fixed Dice Tidus (ID : 800,808,329, IGN : Charles).

Edit 3 : /u/Sunkissed2000 asked an interesing question. Is FD build is better than Aqua Blade build (second BiS on DW) on perfect chain?

Here is my answer :

Spoiler alert: The FD build is winning.

So, on the third turn of each cycle, you're doing more damage with FD versus the Aqua Blade build.

There is an interesting thing.
We see that on T1, AB build does 60% more damages, however, these damages are so "low" compared to the others turns that when you repeat the cycle on the 6th turn, you still outdamage the AB build with the FD one.
