UTD Units

This page focuses on how units are acquired and how they fit into a team. Exact rosters can change with updates, so treat this as a planning helper rather than an authoritative in-game index.

Summon flow

Use this diagram as a mental model: summon results only matter if they improve role coverage and convert into power through upgrades.

How to obtain units

Different units are tied to different systems. Use this section to choose the fastest path for your goal.

Standard Summons

Use Gems to summon units. Typical pricing: 50 Gems (1x), 450 Gems (10x).

Special Banners

Special banners increase odds for specific units. Some banners may require account level milestones (e.g., Level 10+).

Quests & Challenges

Complete quests and event challenges for unique units and materials. Some units are tied to limited-time activities.

Quick tip

If you’re summoning for a specific unit, confirm whether it’s on a featured banner. Random summoning often wastes Gems.

Next step

After you get a new unit, evaluate it by role first (DPS / Support / CC), then use the calculator to compare upgrade paths.
