The Lead Hammer is a slightly stronger version of the Iron Hammer, appearing to look very much alike to the hammer, except for its slight color change. It is one tier below Silver, but it is one tier above Tin. Like all hammers, it is used to remove background walls and create sloped tiles and half tiles.
Its best modifier is Legendary. While Light may seem to provide a better speed boost by percentages, rounding reveals that Legendary and Light mine at equal speeds for this tool.
