Sometimes, you get into stupid situations that you regret with the clarity of a day's rest. Despite having a much weaker power level, we took on Coredlia in Assassin's Creed Valhalla, a Level 340 opponent whose attacks dealt staggering damage. But as you can see, with the bare minimum preparation, defeating this boss is a realistic proposition even with a power level well below 200.
The build we relied on in this fight is exactly the same as the one we used for the Regan fight, so check out that guide for an closer breakdown of that build. Ultimately, her being Level 340 should let you know pretty quickly that her attacks are no joke. But besides that, defeating Cordelia shouldn't prove too difficult, even if she's almost double your level. It took us about a half hour before we were able to take her down.
Given her level, it should be no surprise to learn that Cordelia can dish out a ton of damage. She has access to both of her sisters' attacks, and even seems quicker when using them than the previous two daughters. Her signature move sees her build up some distance between the tow of you and begin casting, after which 3 phantoms will rush after you. You've no other option than to dodge this attack, as if even one of these ghosts hits you, you'll be staggered and the fight will be over before you even know it. Be sure to take you time and chip away at the boss' health bar little by little, as that will help you avoid making the mistakes we made in the video below.
Once you've taken off 50% of her HP, Cordelia will call on the heavens for aid, sending lightning coursing throughout the arena. These bolts are clearly indicated on the ground a few seconds before strike the earth, giving you plenty of time to dodge them. Rush Cordelia down and use an adrenaline attack to interrupt her, after which the combat plays out just like in phase 1, even though she will deal even more damage for the remainder of the fight. Once again, be patient, take it one step at a time, and hit her whenever she raises her dagger and everything will turn out fine.
This final encounter with the Daughters of Lerion will reward you with Thor's gauntlets, the third piece of the thunder god's set. All you need to do now is take the daggers dropped by the daughters and place them in the rear of the statue. Doing so will give you the 4th piece of the set and let you finish this quest-chain in East-Anglia.
