I am not sure if you are aware, there are two healing items that can be made with Tokens of Luck. Festive and Fresh Dumplings that heal 4000 HP over 10 seconds, which is same as the Cokes. You can make 45 for 9 TOL. Rainbow Lantern Yuanxiao that heal 6000 MP over 10 seconds, which is better than Sprite by 500 MP. You can make 45 for 3 TOL. I know that this requires you to sit and make the healing items, but they are free and you get TOL in packs.
