Thermal Ink

Thermal Ink is an ability in Splatoon 2.

Thermal Ink reviles the location of players that the user applies damage to with the user's main weapon as a 'direct hit', meaning that indirect Blaster blasts or indirect hits from a Sloshing Machine or Explosher do not count in this case. The effect lasts for about 16 seconds. Tagged players are reviled by a white silhouette (similar to how the Sting Ray shows opponents), only to the user while roughly 150 DU away from the tagged player and not while the tagged player is submerged in ink.
