If a class suppress another class, it will be getting a class bonus, otherwise no bonus. The class bonus has 4 phases as below:
Phase 1: LV01~09, Attack +1, Defense and Armor +1, Hit Chance and Dodge Chance +10%.
Phase 2: LV10~19, Attack +2, Defense and Armor +2, Hit Chance and Dodge Chance +15%.
Phase 3: LV20~29, Attack +3, Defense and Armor +3, Hit Chance and Dodge Chance +20%.
Phase 4: LV30~30, Attack +4, Defense and Armor +4, Hit Chance and Dodge Chance +25%.

Line Infantry suppress Heavy Cavalry.
Heavy Cavalry suppress Light Cavalry.
Light Cavalry suppress Light Infantry.
Light Infantry suppress Line Infantry.
Artillery and Musician out of this system.

1. Before Class Promotion: The Light Cavalry provide Attack+2, Defense+2 when fighting with a Light Infantry. Therefore, the Minimum Attack and Defense is +3 (Phase 1 ATK +1), the Maximum is +4 (Phase 2 ATK +2) when Light Cavalry fighting with a Light Infantry.
2. After Class Promotion: The Light Cavalry provide Attack+5, Defense+5 when fighting with a Light Infantry. Therefore, the Minimum Attack and Defense is +7 (Phase 2 ATK +2), the Maximum is +9 (Phase 4 ATK +4) when Light Cavalry Elite fighting with a Light Infantry.

1. Common Damage (No Heroic Attack):
Common Damage (1) = [Attack Power from Attacker + Attack Power from Attacker's Weapon + Attack Power from Attacker's Ornament + Attack Power from Terrain + Attack Power from Attacker's Skill + Attack Power from Friendly Unit's Class Buff + Attack Power from Pauline's Inspire Command + Bonus Attack Power from Class Restraint System] - [Defense from Target + Defense from Target's Weapon + Defense from Target's Ornament + Defense from Terrain + Defense from Target's Skill + Defense from Friendly Unit's Class Buff + Defense from Friendly Unit's Skill Buff + Bonus Defense from Class Restraint System]
(In short, just Total Attack Power of Attacker - Total Defense of Target)

1a. Damage without Heroic Attack (Do not include Philipp and Leclerc when they are speed ≥ Target's speed):
Damage (1a) = Round down [Common Damage (1) × Damage Ratio of the Target¹] to an integer + Extra Damage²

1b. Damage with Heroic Attack (Do not include Philipp and Leclerc when they are speed ≥ Target's speed):
Damage (1b) = Round down {Round down [Common Damage (1) × Damage Ratio of the Target] to an integer × Heroic Attack Ratio³} to an integer + Extra Damage

1c. Damage without Heroic Attack for Philipp and Leclerc (When they are speed > Target's speed):
Damage (1c) = Round down {[Target's Current HP - Damage (1b)] × 0.2 + Damage (1b)} to an integer

1d. Damage with Heroic Attack for Philipp and Leclerc (When they are speed > Target's speed):
Damage (1d) = Round down {[Target's Current HP - Damage (1a)] × 0.2 + Damage (1a)} to an integer

2a. Damage without Heroic Attack (Do not include Philipp and Leclerc when they are speed ≥ Target's speed):
Damage (2a) = Damage (1a) + Round down {[Common Damage (1) + Hit Hard Damage⁴] × Secondary Defense Ratio⁵ (If any) × Damage Ratio of the Target} to an integer + Extra Damage

2b. Damage with Heroic Attack (Do not include Philipp and Leclerc when they are speed ≥ Target's speed):
Damage (2b) = Damage (1b) + Round down {[Common Damage (1) + Hit Hard Damage] × Secondary Defense Ratio (If any) × Damage Ratio of the Target} to an integer + Extra Damage

2c. Damage without Heroic Attack for Chasseurs à Cheval (When they are speed > Target's speed) and the units who have the skill "Entanglement" (When dealt damage):
Damage (2c) =Round down [(Target's Current HP - Damage (2a)) × 0.2] to an integer + Damage (2a)

2d. Damage with Heroic Attack for Chasseurs à Cheval (When they are speed > Target's speed) and the units who have the skill "Entanglement" (When dealt damage):
Damage (2d) =Round down [(Target's Current HP - Damage (2b)) × 0.2] to an integer + Damage (2b)

Similarly the Gun Users Formula, just replace the Target's Defense to Target's Armor.

1. Damage Ratio: Default = 1; When the Target is Sailor's Gossip 04 ACE and in our phase, this Ratio = 0.5; When the Target who have the skill will reducing damage for 30% in next fight, this Ratio = 0.7.
2. Extra Damage: For Cosette and Sailor's Gossip 04 ACE (Blade user) only, when they are skill taking effect.
3. Heroic Attack Ratio: Common for our army = 1.5; Light Infantry & Heavy Cavalry & Artillery after Class Promotion for our army = 1.6; Common for enemy = 1.3.
4. Hit Hard Damage: For gun users, this value always = 0; When the Light Cavalry getting a chase-attack and equipped the skill "Hit Hard", this value = 2.
5. Secondary Defense Ratio: Default = 1; When the Target is Heavy Cavalry and have the skill "Secondary Defense", this Ratio = 0.5.

Total Attack Power of Cosette = 28 + Attack Power from Attacker's Skill (Attack +2) + Bonus Attack Power from Class Restraint System (Phase 3: LV20~29, Attack +3) = 33;
Total Defense of Enemy = 8 + Defense from Target's Skill (Defense +2) = 10;
Common Damage (1) = 33 - 10 = 23;
Damage (1b) = Round down {Round down [23 × 1] to an integer × 1.6} to an integer + 3) = Round down 36.8 to an integer +3 = 39

2b. Two Hit Damage with Heroic Attack:
Damage (2b)
= Damage (1b) + Round down {[Common Damage (1) + Hit Hard Damage] × Secondary Defense Ratio (If any) × Damage Ratio of the Target} to an integer + Extra Damage
= 39 + Round down {[23 + 0] × 1 × 1} to an integer + 3
= 39 +26
= 65

The power of HP Recovery = Round down (Musician's Leadership/2) to an integer + the power of the equipped instrument

The power of HP Recovery with Heroic Attack = Round down {[Round down (Musician's Leadership/2) to an integer + the power of the equipped instrument] × 1.5} to an integer

1. Common Morale:
Common Morale (1) = Round down [(Leadership from Character + Leadership from Ornament + Leadership from Skill) × 1.5] to an integer + Morale from Weapon or Musical Instrument + Morale from Ornament (What we see on the character information panel when mission is starting)

1a. Morale with Heroic Action:
Morale (1a) = 0

1b. Morale without Heroic Action (The Target still on the map after fighting or using music):
Morale (1b) = Common Morale (1) + Morale from Character's Skill + Morale from Friendly Unit's Skill Buff

1c. Morale without Heroic Action (The Target was defeated after fighting):
Morale (1c) = Morale (1b) + 10

2a. Morale with Heroic Action (The Target still on the map after fighting):
Morale (2a) = 0 + Morale (1b)

2b. Morale without Heroic Action (The Target still on the map after fighting):
Morale (2b) = Morale (1b) + Morale (1b)

2c. Morale without Heroic Action (The Target was defeated after fighting):
Morale (2c) = Morale (1b) + [Morale (1b) +10]

1. Common Morale:
Common Morale of Lannes (1)
= Round down [(Leadership from Character + Leadership from Ornament + Leadership from Skill) × 1.5] to an integer + Morale from Weapon or Musical Instrument + Morale from Ornament (What we see on the character information panel when mission is starting)
= Round down [(13 + 0 + 0) × 1.5] to an integer + 5+ 0
= Round down [(19.5] to an integer + 5
= 24

1a. Common Hit Chance:
Common Hit Chance (1a) = (Total Scout × 1.5 + Total Leadership ÷ 2 + Hit Chance from Weapon) (Displayed in white text in the properties panel.)
+ (Class Buff Hit Chance from Friendly Unit + Additional Hit Chance from Battlefield) (Displayed in green or red text in the properties panel.)

Hit Chance on the character information panel:
= Round down [Common Hit Chance (1a)] to an integer

1b. Common Dodge Chance:
Common Dodge Chance (1b) = (Total Speed × 1.5 + Total Leadership ÷ 2 + Dodge Chance from Weapon + Additional Dodge Chance from Terrain) (Displayed in white text in the properties panel.)
+ [Class Buff Dodge Chance from Friendly Unit + Additional Dodge Chance from Battlefield + "Disturb" Skill Dodge Chance (If any and it is taking effect)](Displayed in green or red text in the properties panel.)

Dodge Chance on the character information panel:
= Round down [Common Dodge Chance (1b)] to an integer

2a. Hit Chance in Fighting (Hit Chance from Attacker of the damage preview panel):
Hit Chance (2a) = Common Hit Chance (1a)
+ Skill Hit Chance from Attacker + Bonus Hit Chance from Attacker's Class Restraint (If any) + Friendly Unit's Skill Buff Hit Chance (Provide by Murat only)
- [Common Dodge Chance from Target(1b) + Bonus Dodge Chance from Target's Class Restraint (If any) + Skill Dodge Chance from Target + Skill Buff Dodge Chance from Target's Friendly Unit (Provide by Murat only)](If value < 0, return 0; If value > 100, return 100)

= Round down [Hit Chance in Fighting (2a)] to an integer

2b. Dodge Chance in Fighting (Hit Chance from Target of the damage preview panel):
Hit Chance (2b) = Common Dodge Chance (1b)
+ Skill Dodge Chance from Target + Bonus Dodge Chance from Target's Class Restraint (If any) + Skill Buff Dodge Chance from Target's Friendly Unit (Provide by Murat only)
- [Common Hit Chance from Attacker(1a) + Bonus Hit Chance from Attacker's Class Restraint (If any) + Skill Hit Chance from Attacker + Skill Buff Hit Chance from Attacker's Friendly Unit (Provide by Murat only)](If value < 0, return 0; If value > 100, return 100)

= Round down [Hit Chance in Fighting (2a)] to an integer

3. Heroic Attack Hit Chance = Hit Chance (1a or 2a) × 2 (If dual hit, for first hit only.)

-All speeds of these formulas do not include "Speed Check".
-What is the difference between Class Buff and Skill Buff?
Class Buff: That the Buff is provided by the Class of the unit. We can see the units who will show a human icon when clicking a unit before it ends the action. (e.g., Musician, Line Infantry)
Skill Buff: That the Buff is provided by Skill of the unit. We cannot see the human icon when clicking a unit before it ends the action. (e.g., Murat's "Gorgeous Clothing" skill, d'Éon's "Guard" skill)

P.S.1: To get the EXP, we need to dealt damage first. (Does not include the percentage damage, such as Artillery and Chasseurs à Cheval's skill)
P.S.2: One fighting one calculation. Even though chase-attack, that just one fighting.

1. Common Experience (No Heroic Action & the Target still on the map after fighting or music supporting):
Common Experience (1) = Round down {[(Target's LV - Our Attacker's LV) × 2 + 10] × Skill Ratio¹} to an intege;
Then check: If the result ≤ 0, Return 1; If result ≥ 100, Return 100;
Therefore, if we haven't a Heroic Action, the Minimum EXP = 1; the Maximum EXP = 100.

1a. Experience (No Heroic Action and the Target was defeated after fighting):
Experience (1a) = Common Experience (1) × 2 (Double Experience);
Then check: If the result ≤ 0, Return 1; If result ≥ 100, Return 100;
Therefore, if we haven't a Heroic Action, the Minimum EXP = 1; the Maximum EXP = 100.

1b. Experience (With Heroic Action and the Target still on the map after fighting or music supporting):
Experience (1b) = Common Experience (1) (If result ≤ 0, Return 0; If result ≥ 100, Return 100);
Then: Experience (1b) + 10 (Heroic Action Bonus);
Therefore, if we have a Heroic Action, the Minimum EXP = 10; the Maximum EXP = 110.

1c. Experience (With Heroic Action and the Target was defeated after fighting):
Experience (1c) = Common Experience (1) × 2 (If result ≤ 0, Return 0; If result ≥ 100, Return 100);
Then: Experience (1c) + 10 (Heroic Action Bonus);
Therefore, if we have a Heroic Action, the Minimum EXP = 10; the Maximum EXP = 110.

1. Skill Ratio: Default = 1; If Aimée and Eugénie equipped the skill "Proficiency", Skill Ratio = 1.2. "Proficiency" unlock from LV10 and providing 20% experience.
