FAQs
Is Cool Steel good?
It is one of the better 3-star sword options for more offensive characters, with its %ATK substat. Its passive somewhat gates its usefulness to only characters who will be constantly applying Hydro or Cryo in order to maximize its effectiveness, however.
Who are some of the best users of Cool Steel?
Xingqiu and Kaeya will find it serviceable, as they both are capable of reapplying the elements needed in Hydro and Cryo respectively in order to keep its passive activated.
Where can you find Cool Steel?
It can either be found in chests about Exquisite quality in Mondstadt, or it has a chance of appearing as a reward for wishes when rolling on any of the major banners in Genshin Impact.
Final Thoughts
As long as you use characters who can constantly apply Hydro/Cryo, Cool Steel is one of your better options for damage dealing out of the 3-star lineup. Still, if possible you should look to craft or acquire via wishes a 4-star or better weapon as it is limited by its inferior base stats.
