Busty Day Exchange Shop - What to Buy

Event December 18, 2025 By Boring877

During Busty Day, you earn Big Bust Emblems based on your stamina consumption. Each stamina spent gives you one emblem. On a typical day, you can expect to earn around 500 to 700 emblems depending on your playstyle.

If you're saving for Busty Day, you can stockpile stamina items in your mail and use them all during the event to maximize your emblem gains.

Spending Priority

1. 25% OFF Coupon (Top Priority)

Grab this first. The discount value is significant and you can only get one.

2. Memory Crystal

At only 2 emblems each with a limit of 100, this is excellent value. Prioritize these after the discount coupon.

3. Ancient Artifact Coin or Regol Coin

Both cost very little and provide solid value. Ancient Artifact Coins cost 2 emblems each, while Regol Coins give you 10,000 coins for just 1 emblem.

4. ★5 Accessory Box, Summon Ticket, SSR Paladin's Bond

These are fine to pick up if you have spare emblems.

5. Too Expensive - Skip These

The following items cost too much for what they offer:

  • Extermination Spear
  • Extermination Spear Exclusive Limit Break Material
  • Extermination Staff
  • Extermination Staff Exclusive Limit Break Material
  • Raid Battle Ticket Box
