I accidently zoned out some Funnel bats from under the lower part once. I went in, accidently aggroed, and warped out. Imagine my surprise when I found they were still hitting me.
I ran, but didn't get too far. Imagine, the funnel bats mixed in with the ding bats in the lower areas... it wasn't a pretty sight.
You CAN zone mobs through that little warp above ground... but I'm not sure what causes it. I used to abuse those funnel bats to get myself some WS levels. I'd attack til I was low hp, and zone back out. Heal, and repeat... til this one time... :D
Somehow I don't believe that. To get to the extremely hard area of this tomb you need to warp into it. So that means the WAR would've had to take the Ghost through the warp, but zoning removes all hate. Not that you can zone at Spook anyway, I've camped him several times, so I'm quite speculative about him being zoned into the lower level area.
