Awright, so I got lucky and got a double UV on a brandish while crafting.

Slime High
Fiend Med

Ive been asking my friends, and they said that its worth around 20k cr... Im really not sure if its worth that low, could someone please help me out here? I know that ASI and CTR are really good for brandishes, but I figure that the slime bonus would be good for an acheron.
Thanks in advance :)

PS if anyone is interested in buying it, im selling, pm me (fruits-with-guns)
