Tar elementals are the only mobs in UGC that drops money. The money they drop isn’t stellar…maybe 5s average per mob. Not so great after Burning Crusade for high levels, but they drop so fast it’s hilarious. But they also drop Living Essence, at a rate of about 4-5 an hour for me. AND they drop herbs that sell well, such as Blindweed. So even if you’re not an herbalist you can get in on the herb market. The drop rate for green items is also fairly decent for these, and even the GRAY items here can sell for over 1g to a vendor. I have even gotten a Lei of Lilies (epic – sold for 200g) off of one of them. If you are an herbalist, this area has some high-value herbs which can even respawn while you’re grinding away. Of special note: These things are VERY vulnerable to Fire. While Fire mages generally have a hard time soloing mobs, these things go down QUICKLY to fire! Being a fire mage myself, this is probably one of my favorite spots to grind, because of the herbs collected, herbs dropped, green and gray items, Living Essence and silver. Remember to collect Un’Goro Soil, too…to sell or use with your seed packets.
