Koshchey

The koshchey is one of the strangest and most dangerous creatures in The Witcher: a big, spider-like monster with long limbs that reach further than Geralt’s sword. It is not something you stumble upon in the wild. In the game it is conjured by the Salamandra mage Azar Javed as a last line of defence, and it is a fight many players remember as one of the hardest in the whole game.

In The Witcher

The koshchey appears in Act V, near the end of Sweet Revenge, the quest in which King Foltest gives Geralt his blessing to finish Salamandra for good. After the striga‘s crypt, Velerad sends Geralt to the Old Manor. On the way he deals with Count de Wett and a mutated Rayla, then helps his allies fight off mutated Salamandra in the manor courtyard. Depending on the path, an ally then shows him the way into the catacombs beneath.

In the catacombs Azar Javed slips away from Geralt and leaves the koshchey behind to finish him. Once it is dead, Geralt still has to get through two greater brothers before Javed pulls him into his laboratory for the final duel. Javed’s death reveals that Jacques de Aldersberg, the Grand Master of the Order of the Flaming Rose, was the real power behind Salamandra.

Combat strategy

The koshchey hits from outside your normal range, knocks you down and stuns you, and its blows cause heavy bleeding and pain. If you trade blows with it in the open, you lose. Prepare before you go into the catacombs and fight it on your terms.

Drink your potions before the fight. Tawny Owl for faster Vigor regeneration and Kiss against bleeding are popular choices.
Igni works well. Cast it as often as your Vigor allows.
Use the pillars in the room. Kite it around them instead of standing toe to toe.
Remember its reach: it can hit you over your own attacks, so strike and back off instead of starting long combos.
