At 20 and 21 yes there were some blues... even some LOW blues (not light, but not kind of dangerous either.) However, there were some reds... no, not hunters, just Recusos... and VERY red... or VERY resistant... there was a red one stationed on a hill just counterclockwise from the netherbian exit that was red, hit for high 50sm, and RESISTED druid dot's, even after Tash.
Recuso's come in a WIDE variety of classes... the first one we took down was a paladin, the second a druid, and the third, despite being 'KoD' blue at 21 had the expected number of HPs for that level (19-20 or so), but it hit for 71s and cast nothing... warrior, monk? Too distracted trying to keep it rooted to noticed if it even struck at us or not.
