where's the best place to farm silver werewolves?

[KingBane]

i only have them the prestige to make them spawn on the first stage right now, but i think only like 2 or 3 ever spawn throughout the whole run. is there anyway to make more of them spawn? or do the later stages spawn more of them?

[Bastion]

first map at night on plague level 3 or above i believe. they are tough though so you might only get a couple of kills

[Dym]

Only 2-3 per round is normal, don't think i ever found more. Will just need few runs to get.
