Hey,

To optimize your coupon usage, it is advisable to ac*ulate a sufficient number of coupons for Fukurokumaru's Deals and then allocate them based on the available events and your specific requirements. For instance, if you need Training Potions and Lucky Stars are part of the current cycle, it would be prudent to spend your coupons on the latter. Similarly, if you need Breakthrough Materials and Cave keys and Great Plates are being offered, it would be wise to invest in Great Plates. Ultimately, the most suitable approach depends on your individual needs and priorities.

Hope this helped~
