In AO, my friend and I discovered a way to get this one annoying scrab to die...
In one of the set of doors, I think the first one, there is this one door you go in, and you pop out a well onto a rock platform. below you is a larger rock platform with a scrab on it and a well on either side....
Somehow, we ran and jumped and were able to get the scrab to hit the rock wall,
and he got stuck in the rock, it was such a glitch... And then, on other screens,
that one scrab would be stuck in the terrain still, acting normal, screaming when you chant etc... It is insanity...
