[p]The masteries button now appears locked from the start, with a tooltip telling you to get a mastery slot to unlock it. After getting your first mastery slot, or if you got it before this patch, the button will unlock with an animation.[/p]
[p]Unlocked masteries now show the challenge you already completed in their tooltip details.[/p]
[p]Locked masteries can now be seen in runs via the masteries toggle in the left panel[/p]
