The Evil Witch Minion is the dark version of Hex and one of Kaos’ minions. She is the last of three bosses at the end of the Creepy Citadel level. Dark Witch and the other two minions must be defeated in order to collect the Eternal Undead Source.
This dark version of Hex fires three deadly dark-matter bolts then summons a bone cage for protection as she flings explosive skulls at nearby Skylanders.
