Arithmeticks Calculator
Battlefield Units
What is the Final Fantasy Tactics Calculator?
The Final Fantasy Tactics Calculator, known as the Arithmetician in the War of the Lions version, is one of the most powerful and complex job classes in the game. An Arithmetician wields the “Math Skill” (or Arithmeticks) ability, which allows them to cast spells learned from other magic classes (like Black Mage, White Mage, Time Mage, and Mystic) instantly and without any MP cost. The true power of the Final Fantasy Tactics Calculator lies in its unique targeting system.
Instead of targeting units directly, it uses a two-part mathematical formula to select targets across the entire battlefield. This allows a skilled player to affect multiple units—friend and foe alike—with a single spell. While incredibly potent, the job is balanced by its slow speed and the extensive time required to unlock it and learn its component abilities. Anyone looking to unleash devastating, map-wide magic effects should learn how to use the calculator.
Final Fantasy Tactics Calculator Formula and Explanation
The core of using Math Skill is understanding its “Formula = Parameter + Condition” structure. Every calculation requires you to choose one of each to determine who gets targeted.
The formula is as follows: Spell Target = All units where [Targeting Parameter] is a [Numerical Condition]
Step-by-Step Derivation:
- Choose a Learned Spell: Select a spell you have already learned as a White Mage, Black Mage, Time Mage, or Mystic. Note that not all spells are compatible with the Final Fantasy Tactics calculator.
- Select a Targeting Parameter: This is the character attribute you will test.
- Select a Numerical Condition: This is the mathematical rule applied to the parameter.
- Execution: The spell is instantly cast on every unit on the battlefield (allies and enemies) whose parameter value satisfies the condition.
Variables Table
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Targeting Parameter | The character stat to be evaluated. | Level, CT, EXP, or Height | Varies |
| Numerical Condition | The mathematical rule applied to the parameter. | Multiple of 3, 4, 5, or Prime | N/A |
| Level | The character’s current job level. | Integer | 1 – 99 |
| CT (Charge Time) | A character’s readiness for their next turn. | Integer | 0 – 100 |
| EXP (Experience) | A character’s current experience points. | Integer | 0 – 99 |
| Height | The vertical position of the unit on the map grid. | Integer (or Integer + 0.5) | 0 – 20+ |
Practical Examples of How to Use the Calculator
Example 1: Mass Haste
A common strategy is to manipulate your party’s levels to easily buff them. If most of your party members have levels that are a multiple of 4 (e.g., Level 24, 28, 32), you can cast Haste on all of them at once.
- Spell: Haste (Time Mage)
- Inputs: Parameter: Level, Condition: Multiple of 4
- Output: Haste is cast on all units on the battlefield whose level is 4, 8, 12, 16, etc.
- Interpretation: This is a highly efficient way to give your entire party a speed advantage at the start of a battle, a key tactic for any Final Fantasy Tactics calculator user.
Example 2: Devastating Holy Attack
Holy is a powerful White Mage spell that can be turned into a potent offensive weapon. By using Height and Prime Number, you can target specific enemies while potentially avoiding your own units.
- Spell: Holy (White Mage)
- Inputs: Parameter: Height, Condition: Prime Number
- Output: Holy is cast on all units whose map height is a prime number (2, 3, 5, 7, 11, etc.).
- Interpretation: This requires careful positioning. By moving your own units to non-prime height tiles, you can unleash a devastating attack on multiple enemies. This is an advanced technique demonstrating why knowing how to use the calculator is so game-changing. For more on advanced tactics, see our advanced strategies guide.
How to Use This Final Fantasy Tactics Calculator
This tool helps you visualize and predict the outcomes of the Math Skill before you commit to it in battle.
- Set the Formula: Use the dropdown menus to select your desired ‘Targeting Parameter’ (Level, CT, etc.) and ‘Numerical Condition’ (Multiple of 4, Prime, etc.).
- Add Units: Click the ‘Add Unit’ button to create entries for each character on the battlefield. For each unit, enter a name, specify if they are an ‘Ally’ or ‘Enemy’, and fill in their current stats (Level, CT, EXP, Height).
- Calculate Targets: Press the ‘Calculate’ button.
- Analyze the Results:
- The Primary Result will list the names of all units that will be hit by the spell.
- The Intermediate Values show a quick count of affected allies and enemies.
- The Target Summary Table and Dynamic Chart provide a detailed, unit-by-unit breakdown of who is targeted and why.
- Make a Decision: Based on the results, you can decide if the calculation is beneficial (mostly hits enemies) or detrimental (causes too much friendly fire). Adjust your party’s position or your formula and recalculate. Mastering this process is the key to becoming a pro Final Fantasy Tactics calculator.
Key Factors That Affect Arithmeticks Results
Several factors determine the effectiveness of a Final Fantasy Tactics calculator build. Understanding them is crucial for strategic success.
- Unit Levels: This is the easiest factor to control. Keeping your party’s levels aligned (e.g., all multiples of 4, or all odd numbers) makes it easy to apply party-wide buffs while avoiding them with offensive spells. Check our leveling guide for tips.
- Speed and CT: A unit’s Speed stat directly influences how fast their CT fills. Faster units act more often. Using “CT” as a parameter is powerful but unpredictable, as values are always changing. A common tactic is to use `CT / Multiple of 4` or `CT / Multiple of 5` which often hits the active unit, as their CT is 100.
- Map Height: Every tile has a height value. This is a powerful factor for targeting but requires careful positioning of your own units. It’s a key skill in learning how to use the calculator effectively.
- Experience (EXP): Like CT, EXP is constantly changing as units perform actions. It’s a less reliable parameter for precise planning but can be useful for random, chaotic effects.
- Party Composition: A successful Arithmetician needs a party that supports them. This includes having front-line fighters to draw attention away from the slow Arithmetician and ensuring your party’s stats don’t make them vulnerable to your own spells. Explore our party composition guide for more ideas.
- Learned Spells: The Final Fantasy Tactics calculator is useless without a good library of spells. You must invest time in learning powerful magic from the Black, White, Time, and Mystic job classes.
Frequently Asked Questions (FAQ)
1. How do I unlock the Arithmetician (Calculator) job?
You must reach Job Level 5 in White Mage, Job Level 5 in Black Mage, Job Level 4 in Time Mage, and Job Level 4 in Mystic on the same character.
2. Why is my Arithmetician so slow?
The Arithmetician job has one of the lowest base Speed stats in the game. It is often recommended to learn the “Math Skill” ability and then switch to a faster job (like Black Mage or Time Mage) and equip it as a secondary command.
3. Why can’t I use Math Skill in battle? It’s grayed out.
To use Math Skill, you must learn at least one ‘Parameter’ ability (like ‘Level’) AND one ‘Condition’ ability (like ‘Multiple of 5’) from the Arithmetician skill tree. You also need to have learned a compatible spell. Knowing how to use the calculator starts with learning the basic skills.
4. Can the Final Fantasy Tactics calculator target itself?
Yes. If the Arithmetician’s own stats match the formula, they will be included in the spell’s targets. This can be used to your advantage, such as casting Haste on yourself.
5. How do I avoid hitting my own party members?
Careful planning is key. Manipulate your party’s levels and positioning to exclude them from harmful spell formulas. Alternatively, equip gear that absorbs or nullifies the spell’s element (e.g., a Flame Shield to absorb Fire spells). This is a core part of the Final Fantasy Tactics calculator strategy.
6. What are the best spells to use with Arithmeticks?
High-impact spells are best. For offense, ‘Holy’, ‘Flare’, and ‘Toad’ are excellent. For support, ‘Haste’, ‘Regen’, and ‘Reraise’ are game-changers. For more on magic, read our complete magic guide.
7. Is the Arithmetician the best job in the game?
It is arguably the most powerful job due to its ability to instantly cast free, map-wide spells. However, its low speed and high setup cost mean it’s not always the most practical choice. For a comparison, see our job class tier list.
8. Which parameter is the best to use?
‘Level’ is the most reliable and controllable. ‘Height’ is excellent for strategic players who can manage positioning. ‘CT’ is powerful but chaotic. ‘EXP’ is generally the least useful due to its constant fluctuations.
