Kill It With Fire (secret achievement)

There's a secret achievement for completing it with all the same company.
If you didn't get this can you get it a 2nd time around by joining another group of the same company?

Thanks for your info.

there is no secret achievement, i beat it with all the same company and didnt get any hidden achievement

There is an additional achievement for completing it with 4 people from the same company... Unfortunately I can't say for sure if you can obtain it after the first attempt.

CONFIRMED! You can go back and complete it again with the same company and get the achievement.
Just look at my history on lodestone.. :)

PS> For this to work you need someone who has not yet completed it to initiate the battle since you can't select it again.

Now I'm going to set up another run with someone in every nation.

grrr by now everyone must have joined a GC. guess i can let a friend rank a mule and join the comapny.
Thanks Haru was feeling down when i learn about this secret achievement earlier and that i missed the chanse to get it :)

*now i need to work on imperial achievements too*

i login and saw a shout for it 3/4 lol , sent a tell was full luckily for me one didn't do GC quests so they swapped him with me :) now waiting for the achievement

Grats.. I am wondering if there is one for completing it with every nation in the pt.

Youshi did say something about that maybe in 1.20 or 1.19b
