Question about a monster ability

If you are playing in the Ruins of Mesnol rn, minor spoilers for a fight you dont seem intend to take anyway i guess.

Hi, WTF is the >Krakens "jet"!<? It reads like there is supposed to have a limit of some kind on it, but there basically isnt???

"Has to be a straight line" isnt much of one in the ocean, so unless you cram it into a maze it basically just has a 280ft swim speed, faster than anything else in the game, without provoking reactions!? With a 60ft reach attack, high fortitude and athletics(good luck with grappling), how do you pin that down? Theres a few long range damaging spells, sure, but thats kinda it.

I just dont think thats the type of monster that should be doing hit and runs at 150kmh(95mph) underwater
