Fun/efficient chanter charm leveling spots

[dscar23]

Like the title says I am looking for some enchanter charm spots besides the monotonous caiman/crocs and karana beasts. I am currently 18 and I am looking for some good places to level, preferably indoors for the xp bonus.

I know there's other threads similar, but I looked high and low and could not find a thread specifically for good charming spots. I was considering maybe the spiders in guk, or perhaps guards somewhere? Currently at nektulos forest but I don't think the guards spawn often enough to make this a worthwhile location.

Any info would be greatly appreciated, and thanks in advance!
