Where should I get 99 defence with charms?

I'm a maxed 90 defence with 67 summoning, I got like 80-98 str, 80-97 att and 80-90 def all at yaks, so I got no charms whatsoever. I was planning on getting 99 def at frosts but all frost bots are far too detectable. Where should I bot with perfect fighter to get 99 defence and plenty of charms?

 

armoured zombies?

 

Perfect fighter doesn't have altar support, otherwise I'd be doing them.

 

Black demons in the chaos dungeon have a good charm rate, and are good XP.

 

Ankou are good, i remember they also give good profit. Best way to train at ankou would be with bones2peaches tabs.

 

I like Rock Crabs but that just because, my old summoning pure was low level.

 

yea i would say ankou

 

Dust Devils/Waterfiends

Ankous only drop golds which are horrible for training.
