Dnf: I bought a pink suit, called the ancient shooter secret skill. When you want to use it, say something is not purified. What happened?

This is an alien equipment, also known as the scarlet letter equipment. Such equipment needs to be purified before it can be worn. . Need to go to Clent's to buy the design of the book "Purifying the Breath of Another World"! ! ! After purification, the equipment will have an additional scarlet letter attribute, that is, random strength, intelligence, HP, MP! ! And the strengthening equipment needs to be strengthened by the power amplifier in Clent! !
