[Deepholm] Infinite Humanoid Spawn [Great For Rogue]
The quest Undying Twilight requires you to run to the back rooms of the Temple of Earth to fend off against Twilight mobs. These mobs infinitely re spawn after being killed and there are friendly NPCs there killing them. Now, their re spawn only equates to 122g/hour as a rogue (can't be looted normally)(3,000g per day if afk-pick pocketed), but the thing is, they can be pick pocketed. Since they can be pick pocketed, this would be an ideal location for rogues to farm for their Spinerender.
Happy Hunting
