First of all, let's popularize the knowledge about attributes, namely str, dex, agl and vit. Because there is no concept of hit evasion in this play, dex and agl have no clear purpose except to increase the corresponding sword damage (you can regard it as useless), and vit increases defense and physical strength (but in a small amount), which means that only str, that is, strength, is very useful (bonus).

Then back to the topic, many newcomers have a serious misunderstanding about the choice of equipment, that is, they think that equipment with high stars is good, but it is not. The random variable range of this equipment attribute is very large. You often brush the same equipment and find that it is -7500HP this time and only -400HP next time.

The key is one sentence-find valid attributes and ignore invalid attributes.
