3-star equipment is refined with lv.5 skill of the same kind can upgrade to 4-star equipment automatically, and the hidden skill is random.

No auto upgrade at all. I have 3 star equip with full 5lvl refine.

You must have all three level five skills matched. For example

Lvl 5 immu
Lvl 5 immu
Lvl 5 immu

This will then unlock the fourth lvl 5 immu.

Refine is the only answer, free refine for testing how patience you are or use gold refine for showing how rich you are. In this game money is everything
