This is my strategy that usually gets thru without any pain, though it does require you to know what's behind each door.

The only door you really need to open is the first door on the right. The last doors on the left and right also have some nice treasures I usually get, but nothing essential. The other 3 doors (first left, middle left and right) are basically just traps that make the room harder and should not be opened.

My strategy is to first hug the right wall and open the first door on the right. There's no ruin sentinel inside, so no problem.

Then I back out to the bonfire and proceed directly down the center to the back wall. You should only trigger 0 or 1 statues doing this which you can kill without much issue.

If you want to light the torches, pull a statue over to the back wall and kill him there, because it gets annoying after opening the doors. Otherwise, pull a statue to the back 2 doors for access to treasures. Obviously 1 at a time, and i prefer opening the far left door first since it has the more important stuff in it.
