I'm confused about the Neameto 3rd floor where I have to go through these portal

quote LyssaJ

At the top of the stairs you'll enter a warp point and wind up in a room with two sets of stairs. Zhuzhen will explain that warps are how you get around this area. It may seem confusing at first, but there's only five rooms in this part, really, and warps just move you to different points in each room. Going backwards through the same points take you back on your course until you're in the initial warp room. Emergency escape (i.e., you're at level 20 with only one crucifix to your name and no curative items, so get out of there before game over happens) turn right around and head out the warp you came in through, right above the three small pools of water. For a quick escape, take the stairs up, keep going until you warp to a room with circular paths around a central stairway leading up. Go up the stairs you come out on and make an immediate right to the pathway and go to the end. You'll warp to a circular platform just past where you initially entered the maze. Take the left path until you get to the squared off stairs. go straight instead of going up the stairs and you'll find a dark alcove under the stairs that will warp you back outside of the entry point. Now you can go back down the stairs and to the second floor circles. The shortcut path to get to the next boss and create a new set of circles is take the stairs up, follow the same path as the escape route, but instead of going straight towards the dark alcove, cut to the right and go up the stairs. You'll warp to the foot of the stairs facing up. However, there's treasure and fun in the warp maze, so.. here's the treasure path: down the stairs, go right, go up, cut to the left to get a mind's eye, then right, go up around to the upper path, go left, open the chest for Heretic's Coat, go back to upper path, go up to get V-Blade-Blodauth, go back and cut right around stairs, get fifth key, go left and get talisman of power, go right, return to platform and go left, cut up stairs and go to central stairway. If you get lost, don't get panicky. Just warp around using the items you get from fights to keep you healthy. You should get through it eventually.
