In general, you only get ONE CHANCE at this quest per week per character and you have an exact 1 hour time window to complete this quest. Disbanding and picking it back up does not work. The quest has a 1 hour time indicator and you get a buff called [spell=456024].
For each unique fish out of the 20 available you catch out of the while this buff is up you gain 1x [currency=3055], and if you caught all 20 (in 1 week or spanning over multiple weeks) you get the achievement The Derby Dash and the mount [item=223286]. For completing the quest you gain 10x [currency=3055] and you can choose between 2x [item=224752]/2x [item=225770]/2x [item=225771].
For this week (other weeks below):
- Bloody Perch - [object=451678] (Guaranteed)
- Every zone except Azj-Kahet
- Roaring Anglerseeker - [object=451675]
- Exclusively Hallowfall - Best luck along the southern coast
- Get [item=219006] beforehand
- Spiked Sea Raven - [object=451670] / [object=451669]
General tips and notes:
This is one of the easier weeks with all the fish being able to be fished from one zone, Hallowfall. Focus on getting Bloody Perch first, as [object=451678] is highly contended. Be on the lookout for [object=451671] and [object=451677] as they can also drop from those.
I had the best chance of finding [object=451675] along the south-western coast of Hallowfall for Roaring Anglerseeker. Though the pools might be highly contended during this week. If you're running out of time make sure to buy a [item=219006] and just start fishing in open waters.
Spiked Sea Raven is quite easy to find, especially at higher fishing and perception levels. It drops from a variety of pools, but your best shot is getting this in the most abundant pool [object=451670]. If you're having trouble finding this pool in Hallowfall I recommend going to Isle of Dorne and fly along the coast there! Also be on the lookout for [object=451669] and fish in those whenever you can!
Once you get a Bloody Perch or Roaring Anglerseeker and the pool isn't consumed yet, leave it for someone else!
