My druid was rotting A Savage Kobold near one of the camps, when a Kobold Wanderer wandered by and cast a heal on the Savage before moving on. Fortunately the heal wasn't very much, or I would have been greatly miffed!
These con blue to red to my 19 bard. They are nasty for their lvl though. They stack several dots on you and heal themselves. Better to stick with the non casting kobolds for exp.
