East of Perspice. 1-2 mobs at a time. Humanoids = money, cloth and greens. The Ironvine mobs count as Aelfwars: You need to kill 200 for the Achievement Aelfwar Eradication. ~300 xp/mob at 33. It is not perfect and it's not covering too much space, but the respawn rate is good enough. Enjoy.
*EDIT* I added an alternative: Iron Fall - Iron Vine 2. It covers more ground. You can end up killing up to 3 mobs sometimes. Around [3925, 4367]. Same mobs, same achievement.
