Was watching a slosher video. It seems that the weapon has been changed substantially compared to the alpha one the wep file parameters indicate.

In the testing room, you can clearly see the volume of the ink is concentrated along the main arc of the paint. When he shoots it forward it almost leaves like blaster imprint with a thinner trail of paint leading to a rounded splash near the tip. It seems that this main splash does 70, while hitting with the minor splash (the lagging fall-down paint analogous to the nodmg dropped trails of chargers and mini-bullets of shooters) does 40. Since the main splash travels in a parabolic arc, you can potentially aim far or high angle and still hit with the 70 dmg. In other words the dmg does not scale down based on range (unlike rollers) or flight time(shooters). Also, when you kill an enemy the ink ball continues to travel so it splashes a good amount behind them if you kill them point blank, meaning you can just swim right after a kill. A heavy investment in dmg up (3 mains, 2 subs) could make the indirect splash a 2hko, which could be good dealing with multiple enemies in a line. You could aim above all their heads, and opt out of only hitting one with teh direct dmg, and instead hit them all with the falling dmg, like a ghetto inkzooka. We gunbound boys.
Or since the splash continues on if it kills, you can lob a shot over their heads with no dmg up and do 40 dmg to everyone, and then shoot a direct splash at the first guy and itll bulldoze through all the enemies since each one would be below 70 hp. Weapon seems deeper than I first imagined.
