Boss Strategies

How to Beat Sigurd

• You are invulnerable to any form of damage during this fight.
• Sigurd will lose his right arm again as soon as he drops to about 50% HP. This marks the end of the boss fight.

How to Beat Odin

• You cannot die during this boss fight.
• The goal of this fight is to escape the simulation by reaching the giant door that spawns after your HP drops to zero for the first time.
• Odin will drag you back to the fight if you try to reach the giant door with your axe equipped.
• Unequip your axe via the inventory menu and run towards the giant door to finish the boss fight and trigger a cutscene.

How to Beat Basim

Phase One

• Basim is a very agile and cunning fighter that uses multiple assassin tools and techniques to take you down.
• Basim constantly climbs to the top of the pillars and perform a heavy leaping attack towards you. Dodge out of the way at all times.
• Basim constantly drops smoke bombs to disorient and stun you. Anticipate these throughout the fight.
• Basim does not have a health bar for the entirety of this boss fight. The goal is to simply survive and deal as much damage as possible until the next phase.

Phase Two

• Phase two starts in the lift that you and Sigurd used to get down to the Isu Vault's central platform.
• Basim will start using his wire to pull you within his range and perform an attack, similar to the Harpoon Impalement ability.
• Basim starts evading attacks more, similar to how Ivarr dodges your attacks during his boss fight.
• Basim is susceptible to stun attacks and parries once the lift reaches a certain height.
• Phase Two ends in a chase sequence back towards the Isu Vault's central platform.

Phase Three

• Phase three starts after chasing Basim all the way down to the central platform of the Isu Vault.
• Perform a stun attack on Basim while he is inside the circle to end the boss fight.
