The Smith is a difficult monster to kill, and is guarding The Horadric Malus that is needed to complete this Tools of the Trade quest D2R Items. Players need not slay the Smith to obtain this item for questing, as they can kite him out of the room and provide a clear path to the Malus.
With the Horadric Maleus in hand fans are able to return to Charsi and get the reward for completing Tools of the Trade. The reward is the imbuement with a specific item, that adds the ability of a random selection added to the part that gears. It is worth noting that players can only imbue the item they wish to imbue as a result, so it's recommended to do not wait until later on in the game, once they possess higher level gear before putting it into the Malus.
It seems Diablo II: Resurrected is moving ahead on some long-promised features, because Blizzard has revealed that the game's Public Test Realm (PTR) will launch tomorrow. Initially it appears that the PTR is primarily being used for the purpose of testing new back-end server equipment, but Blizzard assures players that testing for the update 2.4 which finally brings Ladder Play, is "coming soon."
According to the article, the update 2.4 will include Ladder play (Diablo's name for an extremely competitive Realm in which progress of all players is tracked and ranked) in addition to some changes to mercenaries and a diverse set of adjustments to individual classes buy D2R ladder items. Here's the scoop about mercenaries and ladders below and see the changes coming to various classes, right here.
