Bercthun is a Power Level 340 Zealot, and he can be found wandering on foot in the northern region of Hamtunscire.
Bercthun is one of the handful of Zealots who wander around on foot. He is gigantic and wields a large great axe, which he can set on fire so that you take burn damage over time if he hits you. He also throws mines and spears at a distance if you try to run away for a breather from this fight. He frequently performs strong heavy red attacks that will knock you prone or even damage you for a huge amount of your health (especially if you’re a lower level than him).
Bercthun uses a blend of strong (red) attacks and lighter (orange) attacks. Lighter attacks can be parried, but strong attacks should be dodged at all costs. If you equip the skill Brush with Death you can trigger slowed time periods by successfully dodging an attack, allowing you to get in some uncontested hits.
Hitting Bercthun’s weak points could also be of use. His weak points are on each of his shoulders and his left thigh. When you successfully shoot a weak point, you’ll dramatically decrease his stamina, and if his whole bar is depleted, you can get in a powerful Stun Attack.
When you’ve defeated Bercthun in combat, remember to confirm the kill to complete this Zealot boss fight. You’ll earn a random powerful rune for this fight and a few other supplies.
