Escaped Froglok Slaves?

[SchismBlacksoul]

Newbie question (even though I did play EQ waaaay back when Kunark was still new, I never leveled a necromancer beyond 5, so no experience with doing this quest XD):

I read on the P99 wiki that escaped slaves spawn in the same "slot" as the skippers, but are listed as rare. EXACTLY how rare are we talking here? <_<;; Also, is there any one specific spot that's "the best" for camping skippers/escaped slaves? I keep only finding randomly-scattered ones along the banks near Cabalis. The occasionally-wandering red cons have me too nervous to do any major in-depth exploring on my own, as a level 10 necro. X_____X

Halp...?
