W-Engines in Zenless Zone Zero are analogous to artifacts in Genshin Impact. They can increase the base stats of characters and provide unique abilities. Of course, there are no universal W-Engines in the game, as each hero needs to be equipped individually. However, some items are objectively better than others. We will talk about the best of them in this guide.
Just like with characters, we have divided all W-Engines into categories S, A, B, C, and D, from the most effective to the useless ones.
Note that items in this category are noticeably worse than their C and B-Class counterparts. They should only be used temporarily until you find a better option.
