Spirit boughs are buffs which slot into your weapons, garments, hat, or even some masks!

From your inventory, go to Equipment, go to an item with an empty slot, click "select power", then you can "change power" to slot in a Spirit Bough. You can also "Release power" to upgrade your spirit boughs and other hidden effects for items.

Spirit Boughs are not consumed, and can be freely reapplied and rearranged on any equipment sets. Use whatever is best for your build!

All spirit boughs require only Amber to fully upgrade. There are at present 64 Spirit Boughs in game. There are 174 Spirit Boughs in the game files.
