For this head to Nagrand and be sure to have your secondary skill fishing! You will need to hop servers once you finish the route, but it’s worth it in the end. What a peaceful way to farm for motes of water.
You will be looking to fish from “”Pure Water” Nods that replace other schools of fish. If you want you can fish everything, but the pure water is what hands out the motes. as you can see within 10 minutes I was able to gather 24 motes of water, meaning around 10-20 primal water per hour. It’s not the best but it is peaceful.
