Talking about the unavailability of artifacts

I'm only going to say two things, the analysis pulled from the community players who stole Starcat.

Blade of sanctions

When the enemy has Yang Jian, Lu Bu, and a mage who eats the book of gods, the blade of sanctions will show his effect, making it impossible for the enemy to return blood. However, many players choose the blade of blood and tears instead of the blade of sanctions, and there will be situations where the enemy can't die without returning blood.

Ming Dow Siming

The assassins in Old Enemy are similar to heroes such as Jing Ke, the warrior Lan Ling and the Monkey King. Shooter can often kill the enemy when he takes out a famous knife. After all, he can avoid death once and output more time. Bring your own blood-sucking equipment, and you can use the vacuum period of assassin skills to complete the anti-killing.
