Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
I have to tell you that i have play only 2 games with Caitlyn. But I try ths build and it works really good for me. I can't tell you more, as I have to confess you that I dont know a lot about her.
As you can see i prefer to make her DPS player, with as much Piltover Peacemaker. So you can have always easy kills.
90 Caliber net is usefull to use like flash, as it throgh you back.
As a DPS player these runes are the most suitable.
Sry for bad English.
Hope have help you.
