AfroSaiyan and Karius-Nym, around 2 weeks before Locke came out, made this massive document explaining pretty much every single aspect of Locke. It's still being made, since the guide was made even before the champion came out, but, nonetheless, it is really impressive.

Sora_CAD, literally hours before Locke came out in June 24th, 2026, released the second Locke guide (in this format) ever. The file explains Runes, Items, Tips and Tricks, and how to play the champion. They stream on Twitch, so go check them out!
