The Compass, now revealed to be a member of the Order of Ancients named Vicelin, won’t attack you until you enter his ship or attack him first. This allows you to begin the fight on your terms, and with those springalds situated so close to his ship, it’d be a shame not to utilize one, right? You’ll find one facing him on the southwesternmost ship, so mount it quickly and begin the fight by taking a good chunk of Vicelin’s health from range.
There are a few things to keep in mind once you’re engaged in combat with Vicelin. First, you’ll need to look out for his flail moves. In the same way that Eivor uses their flail with multiple successive moves, Vicelin will strike multiple times after initiating an attack. This will be his normal method of attack which he will use most frequently, and can therefore be blocked or parried.
Vicelin will also use two unblockable / unparryable attacks. One of these is a flail attack which you’ll need to dodge or roll out of the way of, and the other is a grab attack. Both are marked by a red rune aura, so you’ll be able to identify when they’re incoming. Essentially, as soon as you see a red aura around Vicelin, get out of the way either by running around him, dodging, or rolling.
When you’re avoiding Vicelin’s attacks, the skill Brush with Death will prove incredibly useful, as with most boss fights. This will allow you to slow down time for a brief moment as you dodge, providing you with more time to plan your next attack. The flail attack will deal high damage if each hit lands, and will sometimes cause Eivor to fall to the ground. The grab attack will result in Vicelin throwing Eivor to the sides of the ship.
If you find yourself on the ground, you should dodge or roll immediately to avoid Vicelin’s follow up attack. This will sometimes come in the form of a basic or special flail attack, but he will also throw large rocks at you from afar occasionally. These won’t always inflict high damage, but they will interrupt any animation you might have been engaged in at the time. The rocks will also destroy springalds when you mount them.
Unlike most other boss fights, Vicelin doesn’t heal himself. His armor is also relatively weak, so you’ll find that he takes a lot of damage rather quickly, regardless of the weapon type that you use. To make him even more vulnerable, especially to stun attacks, you’ll find weak points on his left and right arm, and on his left leg. If all else fails, remember to use your high damage melee and ranged abilities to bring him down quickly.
When Vicelin falls, be sure to confirm the kill to begin the Order of Ancients cutscene.
