if you’re just looking for the epicentre, it’s probably best to wear full painite theurgist set, and a defense amulet with warding or something
that should ensure that you don’t instantly die if you get struck by lightning
for ship builds, you’d probably want a brig with a lot of speed to outrun the atlantean ships, but also with quite some health so the shipbuilder ability gives more health back. turning speed and ram power don’t really matter that much, since you would probably not need to turn that quickly anyways, and it’s faster to just not bother with the atlantean ships.
and ofc you’d want to use the lead lines as an artifact
then as a strategy you can just spam the navigator ability once it’s ready and sail in a straight line to range 4, and then just sail around there and you should be able to find it if you spend enough time. If your brig takes more than like 2k damage, use the shipbuilder ability to repair it back to full. If your brig took way too much damage, you could also use a repair hammer or cargo after using the ability to save some galleons/cargo with repairing.
(if anyone has any criticism on this, please say so so we can make a more reliable strategy)
