Out of Control!

The Arachnomechanicon has gone haywire and is running amok in Steamfont! Oglethorpe and Emery have requested your help in dealing with the rampaging mecha-monstrosity.
==Steps==
# Talk to Oglethorpe and after a minute the spider takes off down the hill. Once at the bottom it becomes aggro (46 ^). Kill the spider.
#*If you do not follow the spider quick enough, he will despawn. You must wait for him to respawn, and go through the dialog again. If you kill it before accepting the quest it respawns as a non agro version in under a minute; talk with Oglethorpe again and go through the dialoge to respawn.Respawn may have been triggered by hailing Oglethorpe again. Engage it to make it KoS.
#Return to Olgethorpe for the reward.
