Merge Causality

Merge Causality is a system at the Shrine of Causality that allows the player to combine multiple Part 1 versions of the same recruited unit (trained on different lords' routes) into one flexible Part 3 unit. Abilities and Combat Arts carry over from all merged versions, and higher stats take precedence over lower ones. Training the same character differently on different routes gives the merged Part 3 unit access to a wider range of classes, abilities, and Combat Arts.
