It must be ship with its route ending in Rhotano and the time must be the twilight when you get to the last zone. This only happens once every 10 to 22 hours. Check NPC and see the schedule and it will make sense.
And than see my prior post. when you get to the LAST zone on the trip.
Sadly this is a common practice in MMORPGs that have time based subscriptions, not that I mind subscription I love that this game keeps content coming out. It is just the massive RNG and Time Gaps that can mess with your personal schedule should you attempt to complete these achievements.
This fish makes Ruby Dragon seem like a breeze and Diadem Farming entertaining...... If we need examples of time sinks and long waits.
But the completionist in me will keep trying. I am really letting SE know they added way too many ways to not get this one done theoretically I could never get this done ever if I do not get extremely lucky. on avg more than 50% of the time we never even get the spectral current turning the whole trip into a massive time waste.
