The Nekker Contract is a monster contract in Chapter 1 of The Witcher 2: Assassins of Kings, picked up from the notice board in front of the Flotsam inn. Town Chancellor Louis Merse wants the nekkers infesting the swampy forest south of town dealt with.
Nekkers breed fast and travel through underground tunnels, so cutting them down one by one is a losing game. The real fix is to blow up the nest entrances with grapeshot bombs, which traps most of the pack underground and scatters the rest. Merse takes Geralt at his word when he reports back, no grisly proof required. The contract fails if Geralt leaves Chapter 1 before finishing it.
