Is this really the best route to obtain Essence of water?
I've tried farming the various mobs that drop them, and regardless of drop rate, the spawn rate is a joke. I wipe an area, have to go kill 5-10 of something else, then return to kill the 7 or 8 mobs that drop the essence.
Is there an area with abundant elementals that I just don't know about? I've tried the Toxic Horrors in Felwood, and the plague horrors in EPL. Neither has enough mobs to keep me busy for more than 15 minutes.
Who has fished for the stuff, and how viable is this route?
