Deal with troublesome bandits is a quest given by a Guild Master of any town where you hunt down and exterminate a party of bandits, usually 30-40 large. After accepting the quest, the party of bandits will (depending on the party's spotting skill) most likey be seen by the player's party. The quest-specific bandit party will have blue text to distinguish them from other parties. If any other party kills the bandits before the player does the quest is failed.
