Level 120^^^ Epic x4 undead froglok - An endless stream of ghouls comes up from the Font of the Everliving up the stairs and goes down the ramp to the east. At the bottom of this curved ramp they despawn. Follow one of them down the eastern ramp and keep using your [Restored Chalice of Valor] to banish the ones that come up from behind and the static groups on the sides. Once Froppit has been banished the pool will stop spawning more of them.
