It is a very good idea to purchase both an Armor Smithbox and a Weapon Smithbox from Andre of Astora. You will need to purchase Smithboxes on each play through.
With an Armor Smithbox you can reinforce your armour pieces at Bonfires without visiting a Blacksmith.
Not to be confused with the Repairbox, which will only repair wear and tear damage (Durability). The Repairbox is also sold by Andre.

Andre of Astora, the Blacksmith. Will sell you an Armor Smithbox for 2,000 Souls.
