Damage grand charms?

[chodechugging]

Are there any specific areas where you can farm for grand charms that have a higher chance to give you +whatever to maximum damage when rerolled, just like you can farm for potential skillers in act 3 nightmare?

Single player? Single affix charms aint worth rolling on battle net.
Sharp (+10 max, +76 AR) affix is 29 alvl, meaning any regular mob in normal Ancients Way/Icy cellar has the highest chance of spawning Sharp gc (about 1:70 of all gc's).

GC's spawned from Minions and Uniques in those areas will have about 1:75 and 1:79 chance, respectively.

Yeah, single player, thanks!
