Arriving during Halloween 2024 in October, the Ghost Post is a 2×2 haunted mailbox/letterbox possessed by spectral Halloween energy — a ghost of a postbox dripping with supernatural atmosphere. Clearing it costs and rewards Elixir. The Ghost Post cleverly mirrors the Lucky Letterbox from earlier in 2024, creating a fun Halloween counterpart to the CNY letterbox obstacle — both thematically linked but stylistically opposite. Community members appreciated this creative connection between two 2024 obstacles. Many players kept the Ghost Post for its unique dual-concept design — part mundane everyday object, part supernatural horror — calling it one of the cleverest and most inventive Halloween obstacle concepts in recent CoC history.
