FFX-2 99 Chain Achievement

[Kilika]

Already in chapter 4, currently sitting at around level 30ish with no permanent dressphere to play but I'm starting to get curious on this achievement. What dressphere could possibly do a 99 chain on a fiend? I mean, I know it's possible since its there as an achievement but c'mon, making at least 5 chains is already hard what more is 99

This task may sound daunting, but it is possible against Chac, an enemy that appears as a boss on the 80th floor of Via Infinito, and as a regular enemy on floors 81 to 99. Chac is an excellent enemy to perform a chain of 99 against for two reasons: she has over 430,000 HP, allowing you to safely perform over 99 attacks without killing her and ending the battle, and she has a rather long stagger animation. This is important because as long as you are able to attack her before you stagger animation ends, your chain will still increase. This gives you a breathing room of around one or two seconds between attacks if you are not able to attack her right away. There are two methods that can be used to achieve of chain of 99:

1. The first method involves having a party of three Thieves. Because Thieves attack twice in one turn, their regular attacks are very useful in achieving a chain of 99. Equip Yuna and Paine with the Speed Bracer for Auto-Haste to speed up their attack animations. Simply continue attacking Chac with the girls one at a time until you achieve a chain of 99, and Chac will never even get one attack in due to constantly being staggered. Be warned, however, that this method will not work if your girls are at a high level. Above level 90, you will kill Chac before reaching a chain of 99.

2. The second method involves having a party of three Gunners, each with Trigger Happy Lv. 2 and Trigger Happy Lv. 3 learned. Speed Bracers are not necessary for this method, but are recommended. When the battle against Chac begins, wait until your three girls' ATB gauges are all filled up, then unleash the first Trigger Happy. You do not need to begin your next Trigger Happy right away due to Chac's long stagger animation, so you can give yourself about half a second or so to let your previous character's ATB gauge begin to fill. Keep repeating this process until you reach a chain of 99.

I've no idea if anyone has actually tried these methods. But they certainly DO NOT work for me.

Levels are mid 50's.
Even at that, the girls do not act fast enough as THF's to keep a chain up against Chac.
I've tried with the ATB speed at both max and min. At max ATB speed Chac just acts between the attacks still. And can petrify a character within seconds of the battle starting.

Yes, all wearing Speed Bracers. AGI as level 50+ THF's is 62.

I'll try the Trigger Happy method. Though I'll stick them on Highroad Winds for First Strike. Because sitting there waiting for the gauges to fill is pretty much saying bye bye to one of the girls. Not a good start lol.

Trigger Happy was closer.

Left the tiniest pause between Yuna > Rikku. And then again Rikku > Paine. That kept the chain up for 3 Trigger Happys.
By the time Yuna's gauge was full though the chain was dead.

I wonder if hacking their AGI stat up would make them act fast enough as THF's?

Only one way to find out Frank ^^

[LadGaga]

Yeah that worked ^^

Just got them in a nice rhythm where they could just keep up the chain.
Tried auto-battling it for the win after the achievement popped. But the auto couldn't quite keep the correct rhythm going through for the victory. So I'll CONGRATS! it or something probably.

Next stop TREMA!!
