Sharing via SNS

Be on the lookout for diamonds when you awaken your characters into a higher rarity. In this example, our Milla just reached LR, and the share button indicated that sharing it on social media would give us diamonds. It will provide you with 200 Diamonds when you share it.

Where to Use Diamonds

Unit Summons and Pack Purchase

You can use diamonds to pay for several things in the game, but your diamonds will be more well-spent if you exclusively spend them on:

• Character Summons on Invocation of Chance
• Quick Battles
• Tree of Life's Dew purchases
• Discount Packs from Shops/Events
• Key Packs in Special Shop
• Gear Gacha Banner like Invocation of Seraph's Prophecy and Invocation of the Witches' Secrets when you reach the level when you can use Michael gear or use Magic Crystals.

However, use your Diamonds wisely. Do not spend them on items you can quickly get through Events or Trials.

For gacha banners such as the Invocation of Chance or the Invocation of Seraph's Prophecy, we advise you to check for any ticket packs before using Diamonds.
