On this page of the Assassin's Creed Valhalla guide, you will find a walkthrough of the Basim Boss Fight. You will find out when you will face Basim, what types of attacks does he use and how to avoid them, and how to defeat him quickly and effectively.
The battle with Basim takes place during the A Brother's Keeper main story quest. Eivor travels with Sigurd deep into the wilds of Hordafylke to get to Goinnhellir and give worship to the gods. There they plug into the simulation of Valhalla, from which they fortunately manage to escape. Basim appears in the temple and confronts Eivor.
Basim is an extremely fast and agile opponent, who can attack from different angles, and will not hesitate to use clever tricks like smoke bombs. The fight against this opponent is different from all the boss fights you have encountered in Assassin's Creed Valhalla so far. Basim has no health bar and you can deal damage to him only within the stone arena.
If you run into trouble during a fight and run out of healing items, there are mushrooms growing in the corners of the arena that will quickly replenish your missing health points.
Basim will start the fight by attacking from above and will attempt to jump on Eivor from the upper level of the temple. Be prepared to do dodge him, and you'll be able to land some good hits on him to start off the fight.
This opponent will often use smoke screens. Your visibility will be greatly reduced, but you can still deal damage to Basim if you remember his most recent location.
Most of Basim's attacks are indicated by a yellow rune flash - they can be avoided or parried. Beware, however, of attacks signaled by a red flash, which are unblockable and must be avoided.
Ranged weapons work great in the first phase of the battle, especially when used in tandem with the Focus of the Nornir ability to slow down time. By aiming for Basim's head, you can do massive damage with just one missile.
Continue fighting until the platform starts going down - at this point Basim will be able to block projectiles with his weapon (showcased in the above image), so it's a good idea to switch to melee combat.
After a long fight you'll finally be able to overpower Basim, and when he gets down on one knee you'll be able to perform a Stun Attack, cutting his left forearm and removing his deadly weapon - the Hidden Blade.
Basim will try to run away and reach Sigurd - run after him. While jumping between obstacles you will have the opportunity to collect some mushrooms to restore your character's health.
During the second phase of your clash with Basim, you just need to avoid his speedy attack combos and counterattack. The opponent will no longer use sneaky tricks like smokescreens or attacks from above.
If you have a shield, all you have to do is block your opponent's blows a few times and you'll stun him to the point where he falls helplessly to one knee.
Otherwise, lure your opponent to the luminous circle area and then shoot his green glowing arm to stun him.
Perform a Stun Attack and Eivor, though wounded, will hold their opponent and connect him to the mechanism, putting his body to sleep and sending him into the simulation.
