A Sword for Monsters is a side-quest you can complete in the first act of The Witcher 2 Assassins of Kings Enhanced Edition.
The quest allows you to recover the Silver Sword you lost while fighting the Black Dragon during the Prologue (Trial by Fire).
Even if the side-quest becomes available as soon as you start the first chapter, you wont be able to complete it, unless you unlock the main-quest called Indecent Proposal.
The following walkthrough refers strictly to the side-quest A Sword for Monsters, and explains how to finish it and claim its rewards.
A witcher stripped if his monster-fighting sword is like a dwarf without a beard. Geralts silver blade had flown off with the dragon just after his memorable encounter on the walls of the La Valette Castle, so our hero needed a new one.
The best though certainly not the only way to acquire one was to have it forged by the dwarf blacksmith who had a workshop in Flotsams nonhuman district.
When to start
After By the Gods – Stringing Up Sods main quest
In Flotsam, the non-human district is located in the southern part of the city. If you open your map, the blacksmith you are looking for is marked by an orange sign visible on an alley between three houses and the citys southern wall.
His name is Berthold Candeleria, and if you talk to him, ask him to craft you an item. You already have the Witchers Silver Sword Diagram (acquired during A Rough Landing quest) and you probably need some Silver Ore.
Berthold Candeleria is willing to sell you this important resource, if you ask him to trade with you. Purchase 2 units of Silver Ore, then ask the blacksmith to forge you a Silver Sword. New achievement unlocked: Craftsman.
With the sword in hand you can continue to complete additional quests included in the first act.
