This quest really, really sucks.
I got it in 1/1 tries, but my husband has gone 0/3 with dud powder kegs.
Also, the fishing part is awful. We spent 2 hours in Abyssea trying to fish up the Brine Crabs. You only get a bite 1 in every 10 casts or so (I have fishing levelled, my husband does not but this did not seem to change). And the drop item is not 100%. We killed about 25 crabs in those two hours and got 4 drops total.
It takes far too long to do with time being limited in Abyssea. I would prefer to see the item be 100% drop (or at least 50%) or no dud kegs.
