The Blessed Paths is a building that, depending on the materials used, increases Gathering Radius by +1 or +2. It affects water tiles as well as land tiles. Bonuses from multiple blessed paths do not stack. Blessed paths also decrease movement cost for your expeditions within its range.
Blessed paths only increase the gathering range of the village; using specific materials does not add any bonus attraction to your village.
Consider saving researching & building this until the late game, when you have a good idea of what resources are near your village. Since the village can only support a maximum of 10 buildings, it's not always worthwhile to construct this if you already have plenty of the materials available nearby.
