Stalker

Stalkers are swamp-based monsters from Hexen. Their first appearance is in Bright Crucible, the secret level found in the Seven Portals hub. They are normally not seen, but players can tell where they are by the tell-tale awkward-sounding growls from under the water. They mainly inhabit swampy waters but have been known to sometime inhabit clean water as well. Their attack consists of jumping out of the water to slash the player. The mage's sapphire wand continues to damage them until they are killed. They have 90 Hit Points.
