Vaal temple portal lets you go back into maps after dying

If you go into a map, complete the vaal and open a portal to the temple, go in once (not sure if this is required or not). Then if you die on the map, you can go back to the vaal temple from your base, then go back into the portal and it will let you in in even if you have zero lives left.

I did it twice on one map to confirm after hearing a rumor, it seems like it could be considered an exploit.

Just tested it out exactly as you described, it says "you cannot rejoin this area after dying". You probably had more respawns than you thought?

i tried that early today , it didn't work , it probably got fixed.

You need to go into the temple, then go to your hideout from there, then back into the map from your hideout.

After that if you die, the portal in the vaal temple still works.
