How to Use Gems for Grades in Anime Dice
Gems are used to reroll a selected unit's Grade. To find the service, go to the Hub and look for GRADES. Grade records list Income multipliers; they should not be confused with dice Luck or a Trait Reroll.
Source review: 11 September 2026 (UTC+8). This guide uses published instructions and gameplay images, not an in-game test by this site. Exact screenshot patch numbers were not established.
Find the Grades station
The published Hub image shows the GRADES sign on a pink-roofed station to the right of the large TOWERS entrance. A TRAITS sign is nearby, so check the station name rather than entering the first upgrade area you see.
View the published Grades station screenshot. This is a reference to the captured layout, not a promise that landmarks can never move.
Make one manual Grade reroll
The published instructions specify a unit in your inventory and one Gem for a manual reroll. Follow the cost and selection shown by your current menu if they differ from that reference.
- Open the menu at the Grades station.
- Use the + selector and choose the unit whose Grade you intend to change.
- Check the selected unit and its current Grade before spending.
- Use the Gem control for one manual attempt.
- Read the new Grade and remaining Gem balance before deciding on another attempt.
The documented system assigns one random Grade to the selected unit. A reroll is not a guaranteed move to the next rank. This guide does not assume a result lock, pity counter or automatic stopping rule.

Documented Grade Income multipliers
The compared records agree on the following Income multipliers. This is not a roll-chance table.
| Grade | Listed Income multiplier |
|---|---|
| D | 1.1× |
| C | 1.2× |
| B | 1.6× |
| A | 3× |
| A+ | 4.5× |
| S | 7× |
| S+ | 10× |
| Z | 15× |
| Z+ | 25× |
Sources: AwesWikis Grade record and the Bloxodes multiplier table. The viewable A+ through D panel directly displays the lower five entries. The upper four entries are supported here by the published tables, not by a panel we independently viewed.
A better unit Grade is not the same as the same boost to your whole team
A change from A to A+ moves the listed multiplier from 3× to 4.5×. The ratio is 4.5 ÷ 3 = 1.5, or a 50% increase in that multiplier.
Consider an illustrative calculation. Suppose the selected unit currently earns 1,000 Cash per second, the rest of the team earns 4,000, and that unit's entire income scales with the Grade ratio while everything else stays unchanged.
| Cash source | Before | After the assumed change |
|---|---|---|
| Selected unit | 1,000 / second | 1,500 / second |
| Other units | 4,000 / second | 4,000 / second |
| Team total | 5,000 / second | 5,500 / second |
The selected unit gains 50%, but total team income rises by 10%. These are mathematical assumptions, not measured Anime Dice earnings or a verified formula for every modifier combination.
For a personal estimate, use the earnings you actually observe after the change. Do not multiply measured income by Grade a second time. The Rebirth calculator expects total active income in millions per second: 5,500 Cash per second is 0.0055 M per second.
Checks before spending another Gem
| What you are trying to resolve | Check before trying again |
|---|---|
| You cannot find the Grade service | Use the Hub landmark reference and look for GRADES rather than TRAITS or a Shop menu. |
| No unit has been selected | Return to the + selector and confirm the intended unit. |
| A reroll will not start | Check the selected unit, the displayed Gem requirement and your balance. Do not assume that holding enough Cash meets a Gem cost. |
| Total income did not rise by the Grade ratio | Compare the selected unit separately from the whole team, and keep other conditions unchanged when comparing earnings. |
These checks are not a diagnosis of every interface failure. Stop rather than repeatedly spending if the menu or result differs from the documented sequence.
Choose a unit you expect to keep using and set a Gem budget before rolling. This is a resource-management suggestion, not a claim that every player should target the same Grade. For reported codes that may award Gems, use the code list and redemption guide; current redemption and disputed reward quantities remain separate questions.
Do Grades improve Tower damage or dice Luck?
The Grade labels used in this guide specify Income. They do not document a Damage, Health or dice-Luck bonus. Do not treat this multiplier table as evidence that a Grade reroll solves a combat or character-drop problem.
Why are exact Grade chances not included?
The compared pages disagree on some rare-Grade chance entries. A multiplier can be documented without the complete probability model being reliable. This guide therefore does not give an average Gem cost, a guaranteed number of rerolls or an automatic-reroll target based on those disputed percentages.
