The Orichalcum Pickaxe is a Hardmode pickaxe and is the pickaxe alternative to the Orichalcum Drill, having a slower mining speed but longer range and benefiting from mining speed bonuses. Its alternate ore counterpart, the Mythril Pickaxe, is slightly weaker than the Orichalcum Pickaxe.
It can mine any block except Chlorophyte Ore and Lihzahrd Bricks.
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.
