Equipment and crafting upgrades
Harvest seed crafting
Use crop encounters to find a suitable Harvest craft and apply it to equipment with Lifeforce.
Sacred Grove, reached through Harvest portals in maps or its available access point; activate a Lifeforce Collector beside a ready crop.
Repeat with later Harvest encounters as they appear. Crop rewards and craft options vary, so collect and store Lifeforce when no current offer fits; spend it through the available Harvest crafting interface when a useful option appears.
Stop crafting when the item meets its planned upgrade or when the remaining possible changes carry more risk than value; switch to saving Lifeforce for another item goal.
Open a guide to find other locations and see what the item is used for.
