Wight

A wight is an undead, mummy-like creature with dried flesh flaking off its bones, pointed teeth, sharp claws and glowing eyes. Wights are smart and like to be alone. The bestiary warns that one shouldn’t attack them on sight: left in peace they hurt no one and would rather stir foul brews in their cauldrons than fight.

A threatened wight is another story. It can drain a victim’s life force, a bit like a vampire drains blood, and it spits out an ectoplasmic slime that turns almost at once into barghests, spectral hounds that obey the wight. Poisons barely affect it, and although sunlight doesn’t hurt it, it avoids the light anyway.

In The Witcher 3 you meet wights in Toussaint. A wight and its barghest lurk in the cave passage during The Warble of a Smitten Knight. The best-known one is the Spotted Wight in the ruined Trastamara Estate during La Cage au Fou. You can kill it, or lift its curse and find Marlene de Trastamara underneath, which leads to The Hunger Game.

Combat strategy

The fight is really two fights: the wight itself and the barghests it keeps spawning. Clear the hounds first, because every barghest left alive adds pressure while you trade blows with the wight. Then turn to the wight and stay on top of it with the silver sword. Its slime and life drain hurt, so don’t stand in front of it for long. Since poisons don’t do much to it, rely on your blade and signs.

Apply Necrophage Oil to your silver sword.
Use Axii on the summoned barghests to take them out of the fight for a moment.
Kill the barghests before focusing on the wight.
Don’t count on poison effects. Wights resist them.
Remember the Spotted Wight in La Cage au Fou doesn’t have to die: lifting the curse is the path that leads to The Hunger Game.
