Can some one please explain to me how to open the doors inside Incursions?

I fight my way through the mobs get to the doors with the red locks, but i can never get them to open at all :(

makes no sense to me at all, and since im failing I basically get no loot at end.

You are supposed to pick up the stones that drop and then click on the doors to open, but I barely have enough time to kill the boss.

what stones, i have never seen anything drop inside an incursion.

They show up green in Neversink's filter, forgot what they were called, something stone.

all right I'll keep an eye out for them, maybe I have been missing them.

Thanks for the help

Check that your loot filter is set up correctly to include "Incursion Item" items. Stone of Passage isn't currency.

You loot the stones to click on a red door to turn it green.
This will enable a connection in the present (the actual temple) by rebuilding the door to be able to pass.
Don't worry if you messed up, the progress will get saved and you can work on the temple again and again and again, by running more Incursions, even though you already visited the temple in the present time.
