The Swamplord
"The swamplord lowers it horns and prepares to charge....."
"The swamplord closes its eys and ignores those who taunt it."
Swamplord is an Otherworld boss that drops Crests of the Hound used for Frozen boots. As the quote above shows- this boss resists taunts. This boss also has drudge (a attack that slowly drains health) which is a common, but very irritating, attack from kelpies in the area.
