The event pass has two rows: regular and premium. Points can unlock both rows at the same pace, but the premium row is only available to those who pay for it for that event. All unlocked rewards must be claimed before the event expires!
The regular row generally contains energy, coins, XP, roots and herbs, food, region-appropriate materials, and gems.
The premium row contains a costume, more energy and food, green rings, very good equipment, and gems. Once the end of the premium row is reached, additional points unlock gift boxes, which have a random chance of giving energy, gems, food, xp or a green ring. Additionally, buying the premium row will activate a special speed potion for the remainder of the event. If you already have a speed potion active, its time will be added, not lost.
Re-released events do not have the event pass, so most costumes from past premium rows are currently impossible to get if you didn't buy it when the event was first released. However, one is available in the shop for gems, so more may appear later.
