This quest becomes available by speaking to Charsi following The Forgotten Tower quest. Charsi requests your aid in retrieving the Horadric Malus, an enchanted smithing hammer that could be used to aid the Sisters in their battle against Evil. Charsi indicates that she was forced to abandon it while fleeing the Rogue Monastery during the invasion by Andariel.
The Rogue Monastery can be found by following the path through the Black Marsh and the Tamoe Highlands. Once you reach the Rogue Monastery, continue through the Outer Cloister and into the Barracks. The Horadric Malus is located somewhere within the Barracks, guarded by a demon known as The Smith.Take note that the difference in difficulty between outside the monastery and inside it is vast. The monastery contains hordes of baddies that can't be beaten the same way you beat hordes of baddies outside the monastery. Make sure that you are comfortable with the armor you are wearing, the weapon you are wielding and the spells you think of casting before entering this damnable place.
By retrieving the Horadric Malus and returning it to Charsi, you will be able to imbue a piece of equipment with randomly selected abilities. Note that no Magic, Rare, Set, or Unique items can be used. Also note that this can only be done once, therefore, it is recommended that you wait until later in the game, such as Act III or IV, and imbue a higher level item.

NPC Quest Dialog
Akara:"You must find the Malus."
Cain:"The Malus was forged and enchanted by the ancient Horadric Mages during the Sin Wars. When their union dissolved, the Malus was entrusted to the Sisterhood guarding the pass into the East."
Charsi:"The Monastery can confuse even those who know it well. Stay alert in there."
Gheed:"Charsi talks of nothing anymore, but this Horadric Malus. Between you and her my ears need a rest. Just find it and bring it back quickly."
- "I have offered my nomadic phallus, but to no avail."
Kashya:"Charsi is wasting her time and talents using an inferior hammer! Had she the Horadric Malus, she could make the steel sing and craft you a suit of armor as impenetrable as the Great Eye."
Warriv:"Just as an archer needs bow and arrow, or a draughtsman pen and paper, so Charsi needs the Horadric Malus with which to ply her trade."
Akara:"If you can't carry out this quest, how will you face the greater evils ahead?"
Cain:"The Malus has eluded you so far. Well, search thoroughly in the Barracks... That is where the Rogues kept their forge."
Charsi:"The Malus is a Horadric artifact of great power. Please bring it back."
Gheed:"I have heard that you bear us no Malus."
Kashya:"To do battle with Andariel requires more than thick skin and a strong will. You'll want armor and weaponry forged with the hammer's enchantments."
Warriv:"What better opportunity to show your mettle?"
Akara:"Well done, my friend. But remember, the return of the Horadric Malus is but one step in reclaiming the Monastery."
Cain:"The magical effects imbued by the Malus are impossible to predict, but are always to the good."
Charsi:"Oh! Thanks so much for returning the Horadric Malus! I will now imbue one of your items with magical powers."
Gheed:"I guess it's too late to take back some of the names I called you."
Kashya:"Now that the Horadric Malus is back in our possession, we shall use it to deliver a great blow against the Evil which torments this land."
Warriv:"I am glad the hammer has returned and you with it."
