How to get Athena Kegs in season 11?

Could you possibly elaborate on the methods of acquiring Athena Kegs during Season 11? I'm quite interested in understanding the various strategies and approaches that might be employed to successfully collect these kegs. Are there specific challenges or quests that reward them? Or is it primarily through trading or other player interactions? Also, are there any tips or tricks that you could share to make the process more efficient? I'd greatly appreciate any insights you could provide on this matter.
