However, whether the guardian shield needs to be strengthened depends on the individual game strategy and the needs of the players. Strengthening the guard shield can increase its defense ability and durability, thus improving the survivability of the character. However, strengthening the protective shield also requires certain resources and gold coins. Therefore, players need to decide whether to strengthen the guard shield according to their own situation.
If you often play team copies or battles, strengthening the guard shield may make you more durable and improve your survivability. If you prefer to explore the dungeon alone or challenge alone, then strengthening the guard shield may not be so necessary.
To sum up, whether the guardian shield needs to be strengthened is a personal decision, and you can make a choice according to your own game needs and resources.
