How to obtain?
From Standard Banner
The Cool Steel can be obtained from the Standard Banner (Wanderlust Invocation) by spending your Acquaint Fate. You’re guaranteed one of the featured 5★ weapon or character within 90 pulls and a 4★ within 10. The banner is permanent, meaning you can try your luck whenever you like.
Cool Steel – Banner appearance
From NPCs
In some cases, you’ll get a weapon directly from an NPC, and the Cool Steel is one of them. Try helping them in some way, or directly buying it from them. These are usually niche or lore-based items — not meta-defining, but fun to collect and sometimes useful if you’re building around specific teams.
