I killed him 3 times for 3 toons over the last week. The last was a bard who verified his spawn point (using Highsun) ...
He spawns at 2575, -1800. no placeholder (I watched spawn point for 30 minutes ... nothing else spawned there). His spawn time is unknown, I'm guessing 8 hours, based on other posts and the bloodgill marauder. He immediately moves out so the spawn point is useless.
Use a character (Nec1 Shd2 Pal5 Clr9) with "Sense the Dead" to see if he is up. You only need to be in zone; if the ancient jarsath is up, you'll see him, as the spell detects the closest undead in entire zone, and he is the only undead. If he is up, then go looking (with a tracker or sense the dead). If not, do something else; there is no sense slaughtering drolvargs trying to spawn him.
