Undead Viking

The Undead Viking is a common enemy found in the Underground Snow biome. It behaves the same as a skeleton, except it spawns slightly more frequently and jumps higher. These can drop the Viking helmet (2% drop). They are immune to the Poisoned and Venom debuffs. As of the recent update on Jun 4, 2015, the console version drops for the undead viking are the same as the undead miner, so now the viking helmet is unobtainable.
