At level 60-61, places to go for good exp start to become scarce. Our usual exp spot at the Valley of Sorrows was jammed packed since it was a sat night, so we set out to explore and on the advice of some of our higher level friends, try out the exp in the Sea Serpent Grotto.

Not too long after settling into a good chain or too, Yarr popped, and after a brief discussion, we decided to try and take him out (hey, he drops a reraise III scroll, so I wasnt gonna argue ^^). But as soon as we were ready, a VT Water Elemental spawned at our camp, and we hesitated, just long enough for more monsters to respawn and block our way.
After relocating away from the ele, we emptied the area again, then engaged Yarr. He turned out to be pretty easy, even after he used Benediction to fully heal himself. Just keep him silenced and he shouldn't be a bother to a party of 60s.
