Ink Resistance Up

Ink Resistance Up is an Ability that can be found on Gear in Splatoon and Splatoon 2. It affects the movement of an Inkling in the opponent's Ink by allowing more maneuverability and speed while walking or swimming through it.

In Splatoon
Ink Resistance Up is active throughout the entire match, and is used any time the player steps on or swims through enemy ink.

Ink Resistance Up allows quicker movement when in enemy ink. This is especially helpful for the Inkbrush and Octobrush, to move quickly even when turning sharply. Weapons that let the player strafe fast like the N-ZAP and Mini Splatling also benefit from Ink Resistance Up, as small patches of enemy ink will not slow down movement as much.

The ability also reduces the damage taken from stepping in or swimming through enemy ink. 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.

Additionally, Ink Resistance Up prevents the player from appearing on the mini-map after taking damage. Without the ability, players would appear if they accumulated 30.1 damage or more.

It cannot be rolled as an ability for extra slots on gear.

In Splatoon 2
Unlike the previous game, Ink Resistance Up can be found on all types of gear in Splatoon 2. The ability can also be stacked and rolled for in additional ability slots.

Mutual exclusivity
