Autumn Moon

The Autumn Moon is an event triggered with the Suspicious Looking Calendar, which drops from any mob during the months of September through November. It is a fairly easy moon, but it has a steep difficulty curve, so players will want dungeon level equipment to have a chance to survive. Several excellent weapons drop from mobs during this event, and it allows for several powerful Hardmode weapons to be crafted.
