Accessory mechanics

Accessories can be equipped to units to further boost a team's stats or provide additional effects for the equipped unit. Each unit has three accessory slots (Attack, Defense, and Support - for each type of accessory) unlocked at Unit Level 10, 15, and 20 respectively.

Accessory Crafting
Accessory crafting is unlocked after completing Ch 5: Seafloor Sanctuary 2 and be accessed by going to Upgrade > Create Accessories. From this menu, you can select accessory recipes you have unlocked.

Grayed out accessory recipes mean the materials necessary to craft it have not all been obtained.

More accessory recipes can be obtained by completing specific quests.

Accessory Specialties
After selecting a recipe, the game requires you to select a unit you own to help craft the accessory. Depending on the recipe, units will have various aptitude levels of either Normal, Specialty, or Expert. This aptitude level will affect the rarity rates of the crafted accessory as shown in the following table:

Accessory Sigils

 * See also Sigil Auto-Skill, Unit Sigils list

Additionally, the selected unit will also have a set of four Sigils which the accessory can take on.

Accessory Ranks
Accessories will also have a chance of getting 1-5 star rank. The higher the star rank, the more sub skills an accessory will have unlocked at Level 1. This is beneficial because:


 * Low rank accessories will still unlock all the sub skill slots like higher ranks can when leveled up, but this does not guarantee the unlocked sub skill will be desirable even after the level investment. Knowing the sub skills beforehand will allow you to determine whether or not you want to invest in the accessory.
 * Instead of unlocking new sub skills, higher rank accessories will increase the sub skill effect, meaning higher rank accessories will have a higher potential sub skill effect cap.

When leveling an accessory to Level 3, 6, 9 and 12, depending on the rank, the accessory will either upgrade an existing sub skill or unlock a new one. For lower rank accessories, it will first prioritize upgrading existing skills and then start unlocking new skills until there are four sub skills total at Level 12.

The chances of crafting accessories at certain ranks as well as how they affect accessories are as follows:

Accessory Skills
Accessories have various Auto-Skills consisting of:


 * Main Auto-Skill
 * Sub Auto-Skills
 * Sigil Auto-Skill

Main Auto-Skills
Main Auto-Skills are determined by what accessory is crafted. For example, a Power Bracelet will always have a Main skill that boosts ATK. Rarity will also affect how strong the Main Skill is.

Sub Auto-Skills

 * See also Accessory Sub Auto-Skills Table

Accessories have four sub skill slots. The accessory rank determines how many sub skills an accessory starts with. At levels 3, 6, 9, and 12, the accessory will either unlock a new sub skill or upgrade an existing sub skill.

For lower rank accessories, leveling up the accessory will upgrade existing skills first and then unlock the sub skill slots later.

Sigil Auto-Skill

 * See also Unit Sigils list

Based on the selected unit, an accessory will have one of the four sigils from the unit's sigil set. Each sigil has its own effect, with some working standalone and with others requiring a set of accessories with the same sigil equipped on the unit.

The following is a list of all sigils.

Upgrading Accessories
Accessories can be upgraded by feeding other accessories to the target accessory. The amount of EXP an accessory gives depends on its rarity and rank as shown in the following table:

The amount of EXP it takes to upgrade an accessory to each level is shown in this table:

Zel
If a player wishes to, they can also sell accessories for Zel. The amount of Zel received depends on the rarity and level of the accessory shown in the following table:

Knight's League
A player can also choose to sell their accessories in their Knight's League guild to other members for Zel / Blade Diamonds. If an accessory is purchased using Blade Diamonds, it will get converted to Lord Stones.

Equipped, locked, previously purchased, or upgraded accessories cannot be listed for sale.
