Sváfnir, the Clan of the Snake is a DLC for Northgard that introduces a new kind of vikings.
Led by their ferocious leader, Signy, the Spear Maiden, these outlandish vikings arrived on Northgard. These aren't your typical prideful vikings, the Clan of the Snake is known for using any kind of effective and devastating guerilla tactics in order to ravage their enemies. Open warfare is for fools that seek fame and honor.
The war chief in charge of this clan is available at the start of the game. Her martial skills are a tiny bit better than that of a Warrior's, but once Signy grows older, her powers increase exponentially and she unlocks new abilities. “Scorched Earth” is the most potent ability she possesses, and it is unlocked once Signy becomes an adult. With it, she can burn down a tile and give bonus attack to her units and her buildings.
Because of their different understanding of war, the Clan of the Snake has Knowledge like “Guerilla Tactics” that gives bonus attack power to your troops when civilians are slain, and there's “Stolen Lore” which lets you steal the Knowledge from another clan and use it as your own.
Buy the Sváfnir, the Clan of the Snake DLC if you're looking for a brand new way of experiencing Northguard with a Clan that can't win a Fame Victory, but can mercilessly crush their opponents in the most cunning of ways.
