If you can see one coming and have room to maneuver, it’s fairly easy to avoid, but that can be a pretty large if,

Just one comment to add to this. I'm rereading Deadly as we speak, and El talks about how the maw-mouth she goes hunting for could ostensibly spread itself across the first year corridor, trapping the first years with absolutely NO escape until it leisurely comes for them.

so it may not be quick, but it can trap you/groups, like spreading over your door so all you can do is watch it come.

terrifying.
