1. In the game "Fantasy Westward Journey", separation can enhance the survivability: the separation of the square inch mountain can increase the survivability of the character. The character creates a doppelganger, and the character can disperse the enemy's attacks and reduce the damage. This makes the character more durable in the battle and improves its viability.
2. Combat strategy adjustment: Separation can also be used to adjust combat strategy. Characters can use their avatars to attract enemy fire and protect their teammates. The doppelganger can also be used to cast key stunts and increase the output and control ability of the battle.
