To get uniimited Neopoints you must be in Werelupe Woods or at another place with golden grass and a house. The best place to do this is at Werelupe Woods at the golden grass next to the witches hut. There are some bubbles coming up from the swamp next to the hut. Cut the grass down, then go to the bubbles. You will fall into a cave. Find the way out and the grass will be back. Repeat this as much as desired to get an unlimited amount of Neopoints. Be careful, as there are two bubble points in that part of the swamp. This is also a good way to get unlimited Bagus and Rock Mote.
To find the hidden tower, you must have a Meowclops and be in Faerieland. You will find a wand for Roberta, a perfect golden shield for Tor, etc. You will find this tower near the bedroom area.
The first three pieces are on the west bridge that you take in front of the Meridell Castle Gate. You must go in-between two houses and climb up the wooden ladder, then jump onto the wooden plank. When you are on the plank, walk to your left and get that piece. Then, walk back across. Next, climb up the ladder in front of you. Collect the piece up there, then grab the rope. Slide down until you get to the last platform and collect that piece. For the fourth piece, you must go to the recruitment center. When you walk in, go directly ahead and turn right. You will be in the jail. Talk to one of the prisoners and he will trade you 100nps for the hilt. Take all of these pieces to the blacksmith. After you have the completed sword, take it to the master in the pub and he will sign your sponsor papers.
To escape from the Endless Staircase, you must go to the second Quiggle statue. Look at the statue and see if it is pointing up the staircase or down the staircase. Go in the direction the Quiggle statue points until you reach the next statue, then go in that statue's direction. Repeat this until you reach the door at the bottom of the Endless Staircase.
Go to the Swamp Witch and get the Wild Wateroot. She will then tell you where to get the necklace.
When there is a big wall in the way, get the charm from the Werelupe King.
Equip a Nova or Supernova Mote to your shield and sword. Go towards the Darkest Faerie and she will launch a dark cloud that will knock you back. She will then shoot an elemental ball at you. Block it with your shield and it will reflect and hit her. Then, do a combo attack to her (where you swing your sword two times, then swing down; do not do the combo where you jab your sword). Do this two or three times. You will then automatically switch to Roberta. Some monsters will appear and the Darkest Faerie will levitate. You can kill them, but it is not necessary. Fire some magic at the Darkest Faerie and she will come back down to the ground. Then, walk over to her.
He will start off underground. A few vines will come out of the ground. Destroy them, then a regular giant Juppie will drop off the vines on top of the stage. The giant Juppie monster will then appear and start to pound you with his head. Get near the giant Juppie that fell and wait for him to pound. Attack it, and he will get stuck. Go over to his neck and slash away. Repeat the process until he is defeated.
Buy the Knights Sword, then fight the Ixi Chief. The sword should help a lot. Take a couple swings at him, but do not get too far away or he will charge up and attack you with a powerful blow that will not do much damage, but will knock you back. After you get him down to about half health, he will call out his archers. Ignore them; just go after the chief. After about two more combos he will be defeated.
Get on one of the platforms in the swamp and he will spit poison at you frequently. Have a lot of Bagus with you. You also need to have a good mote of your shield and block frequently. When he hisses at you and attacks, block and he will fall down. Use Down Pound by pressing Down + Jump + Attack. After you hit him once, it will be more difficult the second time because he will freeze you if you do not move out of the way fast enough. The third time will be the same as the first time; he will spit poison again, but not try to freeze you. Use Tor because it is easier to defeat him.
