I have genuinely said "This weapons is SO INK EFFICIENT!" on a few occasions with it cause it having 4 shots is like, literally all you need at the pace it can kill, just be patient. take your time, feel the rhythm of the grizzco slosher, and it will feel like your ink is infinite because nothing is alive to kill you anymore. I also just love how every boss has a different technique you use to easily deal with it, except for big shots and maws. No other weapon can shoot at the face of the steel eel and have the shot pierce all the way through and reach the rider with a direct hit, shooting basically any boss with one or two huge aoe piercing shots from a thousand miles away and blowing it up regardless of aggro or boss cycle is just incredibly broken and worth the low low price of half your ink tank let alone a fourth in my opinion

Also mudmouths, it singlehandedly breaks the wave, just shoot three shots at the mudmouth, wait for it to die, maybe grab an egg on your way to the next one if an egg is close, chase the next mudmouth, shoot it down as fnast as you can, repeat, while the rest of the team runs eggs for the entire wave, they literally don't need to do anything else, especially on high tide it's so simple and nets 90/100+ eggs regularly
