(Spoilers) How to solve double dungeons?

[Razor]

I'm talking about the double dungeons in the undead area, with the 4 pillars that cast an elemental effect.

I can't figure out how to solve them. All walkthroughs I found are for the classic game, not EE, and I think the solution might not be the same in both games. I tried several things but nothing seems to work.

Can somebody please post the solution?

This was in a co-op game.

1. Me and my NPC were in the dungeon under the pillars. Co-op partner and his NPC were in the dungeon under the fire elemetals.

2. He told me the order, I clicked them, I told him mine, he clicked them, he got into a fight, I teleported and helped in the fight. One PENDANT dropped.

3. He and his NPC went in the one I was at (under the pillars), I stayed at the one he was at (under the fire elementals). I told him the order, he processed it, he told me the order, I processed it. He got into the fight, I teleported there and one PENDANT dropped.

4. Finally now we have both pendants.

After this, there are secret passages in each dungeon that you need to go in. Just one of you go in one and the other go in the other to get to the separate pedestals. Make sure you both have a PENDANT.

If you do not do this one right, you get bugged. Hope this helps.

ADDENDUM: When I teleported on the second time, I somehow lost my bow. We had to reload and I just ran over there instead of teleporting and that worked fine because the game is paused in combat until you actually get over there.
