The Daily Monster Hunt Challenge adds to the game a sort of daily quests. These are not the adventures that can match the ones designed by CD Projekt RED, however, players who have already discovered all The Witcher 3: Wild Hunt has to offer, are bound to be satisfied.
This modification introduces 'daily quests' into the game, which appear every day on the notice boards in Novigrad, Velen, and Skellige. These quests allow a player to participate in a random monster hunt. Since Gaunter o'Dim is involved in all this, there is a bit of gambling to it. Upon reading the notice from the board, he turns up and invites you to play his game and set the reward - if the chosen monster is killed before the end of the day, a player is rewarded with double of what he agreed to, however, should he default on the contract, he does not get a single coin. Of course, the approximate location of the monster is indicated on the map.
This mod can be installed manually simply by copying all the contents of the extracted archive into the game's main folder and replacing all the necessary files.
