Main Power Up
Main Power Up is an ability in Splatoon 2, added in Version 4.3.0.
This ability is available in both primary and secondary gear slots and has different effects on each main weapon, even inside the same weapon class.
All gear previously available in the shops that had Cold-Blooded were changed to have Main Power Up instead when it was added.
Effects
The effects of Main Power Up are displayed on the Equipment screen on the info tab for the abilities for the currently selected main weapon. The benefits from Main Power Up vary from weapon to weapon. Weapons which acquire increased damage are incapable of decreasing the number of hits required to splat an undamaged opponent, but the damage total for each hit is slightly increased.
Some weapons, like the Splattershot Jr., are granted an increase in ink coverage, allowing the user to get their special weapon quicker. This stacks with Special Charge Up but not with Tenacity since the quick special charge only counts when inking the ground.

Stacking
A graph showing the damage effect for chargers and splatlings.
Calculating damage
A = ability points = 10 × [Main Power Up main slots] + 3 × [Main Power Up sub slots] B = (3.3 * A - 0.027 * A^2) / 100 C = (mid - min) / (max - min) D = min + ( max - min ) * lerpN(B, C) result = [base value] * D
max
and mid
can be found in the game's parameters as DamageRate_MWPUG_High and DamageRate_MWPUG_Mid. For Main Power Up, min
is always 1.0.
lerpN is an interpolation function where:
If C = 0.5 then lerpN(B, C) = B If B = 0.0 then lerpN(B, C) = B If B = 1.0 then lerpN(B, C) = B If C ≠ 0.5 then lerpN(B, C) = e^(-(ln(B) × ln(C)) / ln(2))
For example, Splat Dualies with two primary Main Power Up slots and one secondary Main Power Up slot.
Given: main slots = 2 sub slots = 1 min = 1.0 mid = 1.06 max = 1.16 base damage = 30
A = 10 × 2 + 3 × 1 = 23 B = (3.3 * 23 - 0.027 * 23^2) / 100 = 0.503985906 C = (1.06 - 1) / (1.16 - 1) = 0.375 C ≠ 0.5, so lerpN(B, C) = e^(-(ln(B) × ln(C)) / ln(2)) effect = 1 + ( 1.16 - 1 ) * e^(-(ln(0.503985906) × ln(0.375)) / ln(2)) = 1.080637745 result = 30 * 1.080637745 = 32.41913235
This would appear as 32.4 damage in-game.
Damage cap
After the damage cap is reached, adding more Main Power Up does not increase maximum weapon damage but does continue to increase falloff damage. For example, even if a Splattershot Pro reaches 49.9 damage on direct hits within effective range, the lower-damage hits that occur out of effective range still continue to be boosted by using more Main Power Up.

Trivia
- Main Power Up is one of the first two abilities to be added to Splatoon 2 post-release. However, it remains the only truly unique ability, unlike Bomb Defense Up DX.
- Main Power Up is the only ability to be favored by two brands - Toni Kensa and Annaki.
