Alternative spots levelling from 15-30ish?

[Nihilist_santa]

I am interested in trying Paineel guards. The wiki only list a few skeleton guards and shows them as level 50, the lower level ones the wiki shows it gives negative heretics faction which would be bad. Which paineel guards do you start with at 15? I conned all the guards I could find and found a 2 spawn with 2 yellow and about 8 other reds close by that were in my level range and then the guards by the lift which the wiki says give faction hits.
