Basically for each item you collect, you want to trade it for the highest possible points. This varies based on who you give each gift to(there’s a total of 9 characters you can exchange gifts with). By making these exchanges and stacking trading points, you’ll then be able to trade those points for weapons, armor, items, stuff like that. The number of points you get for each gift exchange depends on two things: 1) the gift, and 2) the character. Some trades will get you 0 points(basically worthless). The best ones will get you 5 points. Scroll to whatever gift(s) you currently have ready to trade, then look for which characters will give you the most points. If any character gives 5 Trading Points for that item, you’ll see that row highlighted in green with bolded text.
