This Mote of Water farming guide will show you the places that I use for farming Mote of Water. There were no major changes to Mote drop rates at Outland, so this guide can be used for Burning Crusade Classic (TBC) and Retail WoW.
Primal Water comes from combining 10 Mote of Water, so if you need Primal Water, you have to farm Mote of Water.
Mote of Water
This farming place is for Retail WoW players only. If you play Burning Crusade Classic, scroll down a bit for the other farming places. But, for retail players, this is the best farming place. They can ignore the rest of the guide. (assuming you have a high-level character)
This is a level 30 raid instance, so lower-level players should check out the alternative places mentioned below. I'm not sure about the exact level, but you should be above level 35 to solo this place.
The Black Temple is located East of Shadowmoon Valley. It's a huge citadel, so you will spot it from far away.
The entrance to the Black Temple is a crack in the wall to the right of the main gate. I made a picture of the entrance since it can be hard to spot.
Once you are inside, you only have to clear the first few rooms until the first boss but don't kill High Warlord Naj'entus, or you can't reset the trash mobs.
Look for these mobs: Aqueous Spawn, Aqueous Lord, and Aqueous Surger. They are all water elementals, so it's easy to spot them. The most Mote of Water will come from two small rooms where you will find a bunch of Aqueous Spawn.
One run takes 3-4 minutes, and you will get around 15-20 Mote of Water. This is by far the most Mote of Water you can get in such a short amount of time.
After you cleared the first area, go outside and reset the Instance by right-clicking over your own portrait, then click the "Reset all instance" button. This restarts the whole instance, and all mobs will be back, but you can only reset an instance 10 times in an hour.
Nagrand - Elemental Plateau
The best place to farm Mote of Water is at the Elemental Plateau in Nagrand. Crashing Wave-Spirits have the highest chance of dropping Mote of Water, and they often drop 2.
Farming Skettis Surgers at Terokkar Forest is another great way to get a lot of Mote of Water. The drop rate is similar to Elemental Plateau in Nagrand, but the mobs are a bit more spread apart.
Farming Enraged Water Spirits in Shadowmoon Valley is also a decent place for farming Mote of Water, but they drop it less frequently. You have to move between these three places and kill all the water elementals.
Farming Muck Spawns at Nagrand is a decent alternative if you can't farm at any of the previous places. They have a lower drop rate, but the respawn rate is fast, and the water there is shallow enough that you don't have to swim.
