Have currents lead into very dangerous areas, but also put them into strategically useful locations for moving around.
An example is: the current leading to the pit should be centered around a highly travelled route, but the end should go into the pit and go down for hundreds of meters, meaning if you cant get out of it quickly enough you will get sucked into the pit, which may drown you.
Or it could be in dangeroud hiding spots around a leviathan area to act as a hazard. If you get caught in one you get dragged into the open where a dangerous creature can easily kill you.

there’s one that just takes you straight to the void lmao
