I turned in bone chips in Kaladim on a Rallos Zek worshipping ogre shaman. A Ball of Golem Clay will get you non-kos to the quest NPC but you will still be KOS to the guard that wanders in the hallway nearby. The guard is on a long respawn timer so killing it yourself on a higher level character or getting someone else to kill it will work.
