You can synthesize items by using Mana and Synthesis Materials.
Two types of items can be created through synthesis: Battle Items, which can be used in battle, and Equipment, which characters can equip.
To synthesize an item, select the recipe for the item you want to make, then select two characters and a synthesis material.
There will be 3 slots for items created. One of the items created is always a synthesis item. The other 2 items can either be a synthesis item or another item.
Matching Gift Colors is important to apply traits
When the characters and synthesis material selected have matching gift colors with each other, their traits can be applied.
・Types of Traits
There are two types of Traits: one for Battle Items and the other for Equipment.
・Traits of characters and Synthesis Materials
Each character has Battle Item Trait x2 and Equipment Trait x1, and each Synthesis Material either has Battle Item Trait x2 or Equipment Trait x2.
When synthesizing battle items, only battle item traits will be applied. The same application goes for equipment and equipment traits.
・Applying Traits to Synthesized Items
The traits applied during synthesis are selected randomly.
For Battle Items, three out of six potential traits will be applied. For Equipment, two out of four potential traits will be applied.
Battle items might receive traits that have no effect when used.
*If you don't use any synthesis material, a "common" trait with no effect will be applied as one of the traits.
*If the gift colors don't match, the traits of the character will not be applied. Instead, a "common" trait with no effect may be applied.
All traits have five levels. The higher the level, the stronger the effect.
Trait levels are selected randomly for each trait applied during item synthesis.
The following methods can be used to increase the chance of applying traits with level 4 or 5, while reducing the chance of applying traits with levels 1 to 3.
・Awaken characters beyond 3.5★.
・Unlock the Synthesis Core panel on Growboard.
・Increase Player Rank.
