Damage

Damage is the attack value dealt by a weapon. The health points (HP) of a player or object must be lowered down to 0 for them to be splatted or destroyed. For example, players have 100 HP, the Rainmaker shield has 1000 HP, and Splash Walls have 600 HP, naturally losing 85.71 HP per second.

Visual feedback

 * When the player accumulates more than 30 damage, an ink effect appears on the border of the TV screen.
 * In when the player gets splatted, an ink effect appears on the border of the  screen.
 * When an enemy player accumulates more than 30 damage, that player's location becomes visible to the team on the map screen.

Healing damage
After taking damage, there is a one-second delay before healing begins. Touching even a small drop of enemy ink on the ground can reset this delay. In humanoid form, players heal at a rate of 12.5 damage per second. While submerged in ink, players heal at a rate of 100 damage per second.

Falloff damage
If a player is fighting outside of the effective range of their weapon, falloff damage will occur. This means the damage dealt is less, often making it necessary to hit an opponent extra times to splat them. This happens because ink is less lethal when it loses velocity, which happens if a player is fighting outside of the effective range of their weapon. When a player is fighting at effective range, a crosshair appears when they point their aiming reticle at someone.

The Slosher and Tri-Slosher are least likely to experience difficulties related to falloff damage because their damage starts very high. Blasters, chargers and the Sloshing Machine are not affected by falloff damage at all. Falloff damage can be mitigated by using Damage Up in or Main Power Up with certain weapons in.

Passive ink damage
Stepping in enemy ink accumulates up to 50 damage, at a rate of 30 damage per second in Splatoon, and up to 40 damage at a rate of 18 damage per second in Splatoon 2. The Ink Resistance Up ability reduces this to 30 accumulated damage, at a rate of 12 damage per second in Splatoon, and up to 20 accumulated damage at a rate of 9 damage per second in Splatoon 2.

Splash damage
Splash damage is damage that is dealt within the effective range of a weapon, but still with reduced damage as a penalty for not aiming well. It is dealt by the blast from blasters and the Sloshing Machine when the player does not land a direct hit, and by rollers when the target is hit by the far left or far right splashes of ink.

Damage in Splatoon
Some damage mechanics were removed in. These -specific mechanics are documented here.

Damage Up vs. Defense Up
The Damage Up and Defense Up abilities interact by canceling the effects of the other. If a weapon starts at dealing 52 damage per shot, it still does 52 damage if the attacker is wearing one main of Damage Up and the defender is wearing one main of Defense Up. But if the attacker is wearing no Damage Up and the defender is wearing three subs of Defense Up, the damage is reduced to 49.6, forcing the attacker to land one extra shot in order to splat the defender. This leads to players stacking more and more of these abilities to counter each other.

Hits-to-splat tables
These images show the hits-to-splat ratios for all possible match-ups of Damage Up and Defense Up, for weapons that deal consistent damage. Weapons that deal consistent damage but never have their hits-to-splat changed are the Aerosprays, H-3 Nozzlenose, Jet Squelcher, Slosher, Sloshing Machine, Splattershot Pro, and Tri-Slosher.

Blasters, chargers and rollers deal variable damage, so they are affected differently. The edge of a blaster blast may become too weak to splat in two hits, and the edge of a Rapid Blaster blast may become too weak to splat in four hits, requiring the blaster player to either use Damage Up or aim their weapon more accurately. Chargers may require an extra hit to splat if the player did not fully charge their shot. Rollers have their effective range slightly reduced by Defense Up, which sometimes results in a different number of hits-to-splat.

Benefits of reaching damage cap
The number of hits required to splat an opponent is determined by the base damage of a weapon. Weapons that need more than one hit to splat have a damage limit regardless of how much damage is stacked. The damage cap is calculated with the formula 99.99/(H-1), where H is the number of hits to splat an undamaged opponent with no Damage Up.

If a player stacks enough Damage Up to approach these limits, then the player will have the potential to need one less hit-to-splat if the enemy steps on the player's ink color. Stepping on player's ink will make the enemy player get stuck and get damage taken over time. Normally, touching enemy ink will accumulate up to 50 damage at a rate of 30 damage per second, but with Ink Resistance Up, only 30 damage can accumulate, and at a rate of 12 damage per second. The closer the player is to reaching a damage limit, the higher the chances to get one less hit-to-splat.

For example, the base damage of a fully charged Bamboozler shot does 80 damage. If the player stacks two mains and five subs of Damage Up to reach the 99.9 damage limit, and if the enemy walks on the player's ink for a split second, there is the potential to splat them in one fully charged Bamboozler shot instead of two shots.

The Splattershot Pro has the potential to splat in two shots instead of three if the player stacks enough damage up to do 49.9 damage per shot and the enemy walks on the player's ink. The Jet Squelcher has the potential to splat in three shots instead of four if the player stacks enough damage up to do 33.3 damage per shot and the enemy walks on the player's ink.

Calculating damage
a = Ability Points of Damage Up = 10 × [Number of Damage Up main slots] + 3 × [Number of Damage Up sub slots] d = Ability Points of Defense Up = 10 × [Number of Defense Up main slots] + 3 × [Number of Defense Up sub slots] A = (0.99 × a - (0.09 × a) ^ 2) / 100 D = (0.99 × d - (0.09 × d) ^ 2) / 100 When Damage Up ≥ Defense Up Damage = [base damage] × [1 + (A - D)] When Damage Up < Defense Up Damage = [base damage] × [1 + (A - D) / 1.8]
