Aside from the Sinful Indulgence and Valentine's Charm Shard, is it worth to farm the coins for other item such as Kurima Chapo, or we farm it instead on normal since the AP Cost for Normal Quest is now changed to 6 AP permanently? To find the answer, we have to do the math : Choco Magic EX 200/29 = 7 7*40 = 280 1 Kurima Chapo = 280 AP Normal Mode 10pcs of Kurima Chapo Diagram = 30 AP (6*5) 8*30 = 240 8*5 = 40 1 Kurima Chapo = 240 AP As expected, normal quest is better. If you have a better place to farm, then the AP cost will be lower than 240. Though it is not advisable to use 40pcs of Skip Ticket to instantly farm 1 Kurima Chapo. As for the Valentine's Charm Shard, purchasable once and will become available once again when the shop reset.
