What is your suggestion?:
Make the revenant entrances either one way, so if you go in then you can't go out unless you teleport
or have a 7 second deadman mode timer where you need to be out of combat for 7 seconds to leave.
Is this in OSRS?:
Yes as seen here.
Has this suggestion been accepted already?:
No
How would this benefit Alora?:
People are always spamming the entrance if a pker is on them and it makes it literally impossible to die in the caves.
