While 'incased' is similar to 'encased,' it's a less common and somewhat archaic spelling. It also means completely enclosed or surrounded, often for protection or preservation. It's essentially a variant spelling of 'encased' with the same implications of security and completeness. Think of a historical text using 'incased' to describe a jewel within a reliquary. While understandable, 'encased' is the preferred modern spelling.
