Certificates of commendation have been added as rewards for completing Wondrous Tails.
These certificates can be exchanged with Khloe Aliapoh for a number of unique prizes.
I wonder if this will be way to get 3 line rewards without getting 3 lines. I'm thinking get X amount of certificates based on how many lines you matched. Then save up certificates over multiple weeks to eventually get the 3 line rewards.
