Unit Inventory Guide

Summon Heroes unit roster key art — The Units panel is where you manage storage, locks, selling, and UnitDex progress.

Your inventory is more than storage. It protects important units, tracks collection rewards, and controls whether you waste or preserve Fusion material.

Sell Mode

Sell Mode is useful for bulk selling units for Coins, but selling is usually not worth it. Most extra units are better saved for Fusion.

UnitDex

UnitDex automatically records every hero you summon. It lets you review stats, abilities, and special attacks, and rewards Gems for new units.

Rarity	UnitDex reward
Rare	25 Gems
Epic	50 Gems
Legendary	100 Gems
Mythic	200 Gems

Locking Units

Lock units you do not want to accidentally sell or use as Fusion material. Use the lock button next to Equip before doing bulk inventory cleanup.

Storage Space

Your current and maximum unit storage are shown at the top of the Units page near the search bar. You can add 20 storage slots for 400 Gems by selecting the plus icon next to your storage maximum. The source guide lists 1,000 slots as the storage cap.

Finding Units

For the full unit list, use the Heroes page. For investment decisions, use the Tier List before spending expensive materials or Trait Rerolls.
