A stamp is added to the player's Stamp Card and a corresponding reward received for every day the player logs in to the game. Stamps are always received in order, so missing a daily stamp will not cause the player to lose a particular day's reward, but rather they will miss out on rewards starting with the final item on the card. Players receive a new stamp card at the beginning of each month.
Stamp cards can be one of five tier levels, with higher tiers offering better daily login rewards. The tier is determined solely by the number of Sacred Crystals (SC) the player spent the previous month (starting 6 AM EST). How the SC were used doesn't matter, whether spent in the Shop, Shrine, or refilling Charisma/Stamina.
Each month's card is independent from the others. Stamp cards reset to the "Normal" tier every new month unless SC were spent to reach a different tier.
SC spending can be checked in the "Stamp Card" menu.
This ticket, only available from the last 2 tiers of the Stamp Card, grants the player 1 guaranteed Platinum or above unit from the Shrine. The ticket is automatically consumed upon retrieval from the player's Present Box. Each unit has the same chance by rarity, and the ticket is unaffected by the Shrine's Chance-Ups.
