Helegling spawns in a little cove off the main path to the Flaming Deeps full of Orcs. She paths from the cove she spawns in, to the entrance of the Flaming Deeps, and back through several of the grodbog camps south east from where she spawns at.

She can be soloed if you are patient and wait to get her out in the open by herself. If you try to pull her when any mobs are around they will jump you.
