Arena points will be reset with the start of Arena Season 6. We encourage everyone to purchase arena items prior to the start of season 6. Please note, any items purchased with arena points before the start of the season will not be refunded in any way once the new season starts.

The 2-hour refund timer for such items will be reset at the same time as the arena points. Also, game masters will not refund arena points for these items under any circumstances.

This is to avoid items being used to bring Arena points from Season 5 over into season 6 by purchasing them before Season 6 starts and refunding for arena points afterwards.
