I just came across Simone the Inconspicuous (https://classicdb.ch/?npc=14527) who was following this little guy. My Felguard was fighting a Gorishi Worker a little closer than I realized to the NPC's. Needless to say, his Cleave hit Simone for 127, and she crit him in retaliation for 890. I didn't realize what had happened, so I was surprised to see Precious daze me and then bite me for 75. He then hit me for 82. Simone never attacked again, and actually said something to the effect of, "Only a fool would remain in this battle. So long, coward." and despawned. I'm like SWEET! This stupid 60 Elite dog is hitting me for 122 I will just own him...

...And then The Cleaner popped (https://classicdb.ch/?npc=14503) - 3 of them.

"The Cleaner hits you for 5584 (crushing) (1396 absorbed)"
"The Cleaner hits Shaathun for 6825 (crushing)"
"Shaathun dies."
"You die."

Point in case - watch your AoE's around this duo.
