The Spectre Pickaxe is a Hardmode, post-Planterapickaxe. It has a mining range boost of three blocks, giving it a long range compared to most pickaxes. It can mine any block except Lihzahrd Bricks. Unlike most Hardmode pickaxes, this one has no drill counterpart.
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.
