Save gems for summons that solve a specific team need, and spend other rewards where they improve a unit you expect to keep. Clear first-time story stages and complete daily or weekly quests before farming advanced modes. Keep Trait Rerolls for a core carry or unusually valuable support, and check the live banner, shop, event track and pity rules in-game before committing a large balance.
What should you spend gems on first?
Gems are most useful when they are converted into an intentional unit summon. Do not spend them simply because you reached a round number or because a banner is about to expire. First identify the role your account lacks—damage, area coverage, boss damage, support, economy or a specific upgrade path—then decide whether the current banner can fill it.
A practical order is:
- Keep an emergency reserve. Hold enough gems for a future banner that directly addresses your roster’s largest weakness. The amount of that reserve depends on the live summon cost and pity rules, which can change and are not established here.
- Inspect the current banner. Read the featured units, summon rates, duplicate rewards, pity or guarantee language, banner end time and whether progress carries over. Treat the wording on the current in-game screen as authoritative.
- Spend only with a roster goal. A summon is easier to justify when it upgrades a stage you currently cannot clear or gives reliable coverage your team lacks.
- Stop when the goal is met. Extra pulls made from habit are usually less valuable than preserving gems for a stronger or better-timed banner.
Secondary guides published on June 23, 2026, consistently advise saving gems for character summons instead of buying rerolls or stat items directly. That is a sound default, but it should not override a live shop offer that clearly has better account value. Compare the current exchange, the time needed to earn the same item through play and the likelihood that the item will be replaced.

Use the banner screen as a checklist rather than relying on an old tier list. A unit’s ranking can change after balance updates, new stages or a new trait system. Evaluate the offer against your account today.
Check the role and replacement risk
- Does the featured unit cover a role no other unit on your account performs well?
- Will it remain useful across the modes you actually play, or is it specialized for one event?
- Can a unit you already own perform the same job after a trait change or upgrade?
- Are you prepared to invest the evolution, upgrade or material costs required to make the unit effective?
Read the rules before pulling
- Confirm the single-pull and multi-pull prices shown now; figures copied from older guides may be wrong.
- Check whether a guarantee, pity counter or exchange token exists and whether it carries to another banner.
- Look for the banner’s end date and time zone so that a planned final pull is not made after the offer changes.
- Verify the actual rate table and featured-unit list rather than assuming every banner uses the same structure.
Use a stop-loss rule
Set a maximum spend before the first pull. If the banner does not produce the role you needed within that limit, keep the remaining gems. Chasing a result after the account goal has become unlikely can leave you unable to participate in a later banner with better coverage.
Best ways to earn gems before you spend them
Early progression generally offers the most efficient, low-risk gem income. Complete guaranteed rewards before investing time in uncertain endgame farming.
| Source | Availability | Who should prioritize it | How to judge its value |
|---|---|---|---|
| First-time story clears | Mostly one-time per stage | New and progressing accounts | High priority because the reward is attached to progress you need anyway. |
| Daily quests | Repeatable on the current reset schedule | Every active player | Complete them when their tasks fit normal play; do not spend premium currency to force completion. |
| Weekly quests | Repeatable by weekly reset | Players who can plan several sessions | Track unfinished objectives early so a reset does not erase easy rewards. |
| Limited-time events | Only while the event is live | Accounts that can clear the event efficiently | Compare the event track and shop with the time and stamina required. Names and rewards change. |
| Codes | Only while each code is active | All players who can verify a current code | Use only codes shown by an official, current channel; old lists often retain expired entries. |
| Odyssey runs | Depends on access and current rewards | Accounts ready for the mode | Measure gems and useful materials per run against clear time and failure risk. |
| Worldlines | Depends on access and current rewards | Players with the required progression | Choose it when the live reward makes the additional difficulty worthwhile. |
The categories above are established as common routes, but exact gem amounts, active codes, event names and reset details can change. Confirm the reward shown in the current quest, event or mode interface rather than budgeting from a third-party list.

Push the main story far enough to unlock systems and claim first-clear rewards before repeating a low-level stage for a small return. A story clear can also unlock better farming options, so its value is more than the gem line on the result screen. If a stage is blocked, improve the weakest link in your team—usually damage uptime, range coverage or survivability—before spending gems on random summons.

Make daily and weekly quests part of your routine
Open the quest panel at the start of a session, note objectives that overlap with your planned farming and leave time for any task that requires a different mode. Quests are repeatable, making consistency more important than a single large payout. If a quest requires a mode you cannot clear efficiently, do not drain resources merely to complete it; return after your roster improves.
Evaluate events by net value
An event can offer gems, summon-related items, Trait Rerolls or upgrade materials, but the headline reward is not automatically profitable. Estimate the complete cost: entry requirements, stamina or tickets, retries, time and the opportunity cost of skipping story or quest progress. Prioritize event milestones that grant account-wide value or materials you would otherwise have to farm slowly. Because event shops and tracks rotate, make the comparison using the live event panel.
Use advanced modes only when your account is ready
Odyssey and Worldlines are additional routes, not universal replacements for early progression. If a run has a high failure rate or takes substantially longer than a reliable alternative, its theoretical reward per clear may not be its practical reward per hour. Record a few normal runs, including failed attempts and consumables, then choose the mode that produces the best dependable return for your current team.

What should you buy with gems besides summons?
Direct gem purchases of rerolls or stat-oriented items are usually a lower priority than character summons because some guides report those resources through play, events, codes or Odyssey. That advice is not an absolute rule: a live shop item can be correct when it completes a guaranteed upgrade for a core unit and the alternative would require excessive farming.
Use this three-question test
- Is the item obtainable through current gameplay? Check quests, event rewards, codes and accessible modes first.
- Does it improve a unit you will keep? Avoid paying premium currency for a temporary unit likely to be replaced.
- What is the opportunity cost? Compare the gem price with the current summon cost, the banner’s guarantee progress and your reserve target.
Do not infer value from an old shop screenshot. Exchange rates, stock limits and featured bundles can be changed without matching older guides.
When should you use Trait Rerolls?
Trait Rerolls should normally go to a unit that is central to your team and likely to remain there. Spend them after you have chosen the unit, understood its role and confirmed that the trait you want actually improves the way you use it.

Good candidates
- A primary damage dealer used in most of your clears.
- A support whose trait changes team-wide economy, cooldowns, range or damage in a meaningful way.
- A limited or difficult-to-replace unit for which a trait upgrade has lasting value.
- A unit that already has the levels, evolution and investment needed to benefit immediately.
Weak candidates
- A starter or filler unit you expect to replace soon.
- A character used only because your roster currently lacks alternatives.
- A unit that is unbuilt, unevolved or unsuitable for the modes you play.
- A unit selected solely because an old guide places it high on a tier list.
A safe reroll procedure
- Confirm the unit is part of your intended long-term lineup.
- Read the current trait pool and identify the acceptable outcomes, not just one ideal result.
- Set a reroll budget before starting and stop when you reach a trait that meets the unit’s job.
- Keep enough rerolls for another core unit if your roster still has an unfilled role.
Trait and unit rankings are patch-sensitive. A named “best trait” from a June 23, 2026 guide may no longer be optimal after a balance change, new unit release or mode adjustment. Use such rankings as a shortlist, then verify the current trait descriptions and community-tested performance in the present patch.
Recommended Free Tools
How to spend other rewards efficiently
Not every reward should be converted immediately. Treat materials, tokens and event currency as targeted tools.
Upgrade materials
Concentrate materials on the units that determine whether you clear a stage. Spreading small amounts across a large bench can leave every unit below an important upgrade breakpoint. Before upgrading, check the next level’s actual cost and whether the unit is part of your planned summon strategy.

Event currency
Buy items with lasting account value first: a guaranteed unit or high-impact upgrade generally outranks cosmetic or easily farmed items. If the event ends soon, prioritize rewards you can afford and use; do not assume unspent currency will carry over unless the event screen says so.
Duplicate or exchange rewards
Read the exchange description for restrictions, expiration and whether the item can be used on your intended unit. Save flexible tokens until you know which role your next summon will fill, unless the token itself expires.
A spending plan for different account stages
| Account stage | Gem priority | Reward priority | Main mistake to avoid |
|---|---|---|---|
| New account | Story-focused progress, then a banner that fills a clear role | Guaranteed quest and first-clear rewards | Pulling on every banner before learning the roster’s gaps |
| Developing account | Save for upgrades that improve several modes | Daily and weekly consistency, then efficient events | Spending gems to bypass materials that can be farmed reliably |
| Established account | Selective limited or role-defining summons | Event shops and advanced-mode rewards after efficiency checks | Chasing marginal duplicates without a defined breakpoint |
| Endgame-focused account | Plan around live banner rules, guarantees and future roster needs | High-value event milestones and targeted rerolls | Assuming an old tier list or pity figure still applies |
Common mistakes and how to correct them
Spending because a banner is temporary
Limited availability does not make a unit necessary. Compare its role with your existing roster and the actual guarantee rules. If it does not solve a current problem, preserve the gems.

Budgeting from unverified numbers
Some secondary pages repeat example summon prices, daily payouts or pity totals that are internally questionable and not confirmed against a current official source. Do not build a savings target from those figures. Use the live game interface for every number.
Rerolling a unit you may replace
Trait Rerolls have higher value when attached to a long-term investment. Delay rerolls on temporary units, even if their current trait looks slightly better.
Ignoring time and failure rate
A mode with a larger listed reward can be worse if it takes much longer or fails often. Compare dependable rewards per hour, including retries and consumables.
Trusting an expired code or event guide
Codes and event shops are time-limited. Verify the date, eligibility and redemption result in the current game before counting a reward in your budget.
Quick Recap
Five-minute checklist before a major spend
- Open the current Summon screen and record the displayed cost, rates, featured units, guarantee language and end time.
- Write the team role you are trying to improve.
- Check whether quests, events, codes, Odyssey or Worldlines can provide the needed resource without gems.
- Set a maximum spend and a reserve you will not cross.
- For Trait Rerolls, confirm the unit is a long-term core and define an acceptable stopping point.
- Recheck the shop and event descriptions for expiration, stock limits and carry-over rules.
What is currently known—and what can change
Guides dated June 23, 2026 support the broad strategy of saving gems for intentional summons, prioritizing story and recurring quests, using events and advanced modes as additional income, and reserving rerolls for core units. They do not establish current banner costs, rates, pity thresholds, exact reward amounts, active codes or event availability. Search summaries for two community wiki pages also surfaced summon or reward information, but the pages could not be opened for verification, so they are not reliable foundations for precise claims.
As a result, treat the live in-game banner, shop, quest, event and trait descriptions as the final authority. Recheck them whenever a patch, event rotation or new summon changes the available options.
Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
