In the game dnf, the way to adjust the color of the stone protector is to find Monica from NPC library in the channel of the devil's war and forge again. Players click Monica in the NPC Library, select the recasting option, open the recasting interface, put the recasting stone that needs to be adjusted in color into the recasting interface, and then consume unstable stone fragments for recasting, and they will randomly get different colors of stone protection.
The color of the obtained guard stone is random, that is, the color of the guard stone itself is purple, green and yellow. After heavy forging, any combination of colors such as purple, blue, red, yellow and green can be obtained.
