Each unit has a size, and it affects their chance of being hit and how much damage they deal.

The sizes can be ranked as follows:


Size and Damage

Units that are larger than the attacker take less damage from their attacks.

For each size difference, a penalty of 10% is applied to the damage. Below is a table showing the specific damage multipliers according to one's size difference:

Attacker Size\Defender Size 3L 2L 1L M 1S 2S
3L 1.0x 1.0x 1.0x 1.0x 1.0x 1.0x
2L 0.9x 1.0x 1.0x 1.0x 1.0x 1.0x
1L 0.8x 0.9x 1.0x 1.0x 1.0x 1.0x
M 0.7x 0.8x 0.9x 1.0x 1.0x 1.0x
1S 0.6x 0.7x 0.8x 0.9x 1.0x 1.0x
2S 0.5x 0.6x 0.7x 0.8x 0.9x 1.0x

The "Ignore Size" pilot skill allows you to bypass size penalties on damage. Some attacks also have a built-in "Ignore Size" ability, which also allow you to deal full damage with your attacks against larger enemies.

Size and Accuracy

Larger units are easier to hit than smaller units.

When attacking any given unit, the following multipliers are applied to your hit chance, based on the size of your enemy:

Size Multiplier
3L 1.6x
2L 1.4x
1L 1.2x
M 1.0x
1S 0.8x
2S 0.1x

Terrain Rankings

Units and their weapons can have Terrain Rankings for Air, Ground, Water and Space. They can go from D<C<B<A<S.

Unit Terrain Rankings

The Terrain Ranking of a unit affects their chance of landing hits and of dodging hits.

The effect that each Terrain Ranking has on a given unit's chance of both landing hits and dodging hits is as follows:

Terrain Multiplier
S 1.1x
A 1.0x
B 0.9x
C 0.8x
D 0.4x

Your unit's evade chance and hit chance are calculated separately from your opponent's. This means that you only need to care about the terrain that your own unit is positioned at in order to get the full benefits of the Terrain Ranking's multiplier for hit chance and dodge chance.

Weapon Terrain Rankings

The Terrain Rankings of weapons affect how much damage they deal.

When attacking with a weapon, its damage will be multiplied by a factor based on the Terrain that the opponent is placed at. The multipliers are as follows:

Terrain Multiplier
S 1.1x
A 1.0x
B 0.8x
C 0.6x


Morale raises naturally as you fight enemies in battle. It increases the damage you deal, decreases the damage you take, and allows you to access your stronger attacks.

Morale normally caps at 150, but this cap can be raised by using the "Break Morale Limit" pilot skill; a variety of parts; upgrading the AOS sub-category: "Sick Bay"; and by using the Supporter "Yuta".

Gaining and Losing Morale

Morale can be gained or lost in a variety of ways. Which are the following:

Action Morale Obtained
Hit an enemy +1
Be hit by an enemy +1
Your unit destroys an enemy unit +3
An allied unit (except the attacker) destroys an enemy unit +1
An allied unit is destroyed +1
Board a battleship (this can't lower your morale below 100) -10
Receive the Resupply command -10

Effects of Morale on Damage

Morale essentially acts as extra stats when calculating damage.

As in, if you have 200 CQB and 100 Morale, when using a melee attack, your damage will be calculated as if you had 300 CQB (200 + 100).

Similarly, if you have 200 DEF and 100 Morale, when receiving an attack, the damage you take will be calculated as if you had 300 DEF (200 + 100).

Critical Hits

Critical Hits deal 1.25x damage.

Having a higher SKL than your opponent increases your Critical Hit Chance based on the difference.

The "Soul" and "Valor" spirits reduce your Critical Hit Chance to 0%, but you may use the "Smash Hit" ExC Command to land a Critical Hit, even while under the effects of "Soul" or "Valor."

Neither "Soul" nor "Valor" affect Support Attacks, so your Support Attacks will still be able to land Critical Hits while you're under the effect of those spirits.

Other Modifiers

  • Each time a given unit is attacked, after the first time they were targeted for an attack this turn, they receive a -5% penalty on their dodge chance. This stacks up to 20 times, for a total of -100% dodge chance.
    • This resets after the end of a turn.
  • Your hit chance is decreased by 3% for each square of distance between you and your target.
  • Surrounding an enemy unit with allied units increases the damage that the enemy takes (the attacker is not counted for this calculation).
    • Surrounding with 2-3 units gives you +5% damage; Surrounding with 4 units gives you +10% damage.
  • Support Attacks deal 50% damage. This can be raised to 75% when using the Supporter "Tatra and Tarta."
