First of all, we need to understand the principle of Feng Shui. Feng shui is a special attribute in the game, which can improve the attribute bonus of buildings or objects. Different feng shui attributes will have different effects, such as increasing Qi and blood, mana or improving defense.
So, is it cost-effective to improve Feng Shui? This needs to be considered according to the specific situation. If your character or pet needs to improve certain attributes, then promoting Feng Shui may bring some benefits. However, if you already have some advanced buildings or objects, the benefits of improving Feng Shui may not be as good as expected. In addition, it takes some resources and time to improve Feng Shui. If you are not sure whether it is worth investing these resources, it is recommended to conduct some tests first or refer to the experience of other players.
In short, whether it is cost-effective to improve Feng Shui needs to be considered according to specific circumstances. If you have any questions or are not sure whether it is worth investing resources, I suggest you refer to the experience and suggestions of other players or consult professional players in the game.
