Experience tokens!

dimi4a

After a player reaches max Level (85) in the game all the Experience earned afterwards from battles and activities is lost. Instead of going to waste it can be stored so it can be converted to Experience tokens, which in turn can be used to buy Shards and Items from a new shop, just like the converted tokens in the Shard shop.
