Easy to farm souls & lots of embers helping people defeat dancer
It's nice that you included drop rates and such things. It's very helpful knowing that this enemy "rarely" drops embers, or that enemy "commonly" drops it. Or that this enemy drops it with an unspecified drop rate. Well done.
It's nice that the pages to certain enemies you linked on this page just don't exist. You're doing a good job
The Lothric caste farm is not bad, though I wouldn't call it a "common" drop. I just did about 25 runs and got about 8 Embers, a few chunks, a sunlight medal and a crap-load of armor, shields and shards. So essentially 8 embers from 75 Lothric knights.

No doubt you would get better results with gold coins, but that seems like a waste.
