Walkthrough

For this quest you’ll need to help Lambert “fortify” Ciri’s cursed Phylactery at the Circle of Elements. You’ll find Lambert inside Kaer Morhen‘s inner keep (#1). When you talk to him there, he’ll hand you the Phylactery, and he’ll begin leading you to the Circle.

The trip will take a while. Along the way, you’ll get attacked by a few level 19 harpies (#2), you’ll discover that Lambert’s boat is missing (#3), and then you’ll find Lambert’s boat (#4) — only it’ll be guarded by a handful of level 17 drowned dead and a level 20 bilge hag. After the battle, Lambert will jump into his boat and take the tiller, and you’ll have to jump in after him and interact with the prow. When you do, Lambert will sail you to the cave leading to the Circle of Elements.

When you reach the cave entrance (Exit A), you’ll hear a boy calling for help. Lambert will figure that it’s a trap, but he’ll go along with whatever you decide to do. If you head west to investigate the matter, then you’ll get ambushed by some level 18 foglets, and Lambert will take the opportunity to insult you.

Inside the cave, you won’t need to do anything other than get to the other side. However, along the way you can loot some chests ($) and fight a cyclops named Old Speartip (#5). Speartip will be sleeping when you arrive, so if you don’t want to tangle with him then you should just stay far enough away so you don’t wake him up. If you do fight Speartip, then be sure to apply Ogroid Oil to your silver sword first. Speartip won’t drop anything noteworthy when he dies other than some monster parts.

When you exit Speartip’s cave (Exit B), you’ll just need to follow the path leading away from it. After a short distance, a trio of trolls will order you to go away. No matter how you respond, Lambert will make them mad, and they’ll start throwing rocks at you. You won’t be able to climb up to the trolls, so you’ll have to flee into a small cave to the north (#6). Inside the cave, you’ll have to use Aard (or your weapon) on a pile of rocks to clear a path to the exit.

When you exit the small cave, the rock-throwing trolls will be waiting for you. If you refuse to negotiate with them or refuse to leave your swords behind, then they’ll attack you. But if you hand over your swords, then they’ll allow you to move through their territory in peace.

At the Circle of Elements (#7), you’ll need to perform a ritual. For your part, you’ll just need to place the Phylactery on the altar and light the four nearby braziers. Then once Lambert has completed his part, the two of you will get to sit down and have a heartwarming conversation about how much Lambert loves being a witcher. Afterwards, you’ll pick up the charged Phylactery, and, if necessary, you’ll automatically collect your swords from the trolls. This will complete the quest and earn you 500 xp.
