Go to the second desert island you can reach, and go into the bowl at night. There are three spawn points. One is next to a rock. Another is behind the tent. The third is on the side of the cliff as you climb down.
Once you collect ten Darkonium Crystals and ring the bell back at HQ, an intermission sequence announcing the finalists will begin. Afterward you are allowed to prepare for the finals. First, go to Palaish Ilse and speak to the person that gave you the clearing slimes tests before. He will giveyou access to Metal Menagerie if you can clear fifteen slimes in five minutes. The number of slimes that need to be cleared increases with each subsequent attempt after entering Metal Menagerie for the first time. Once in Metal Menagerie, cast Vanish on yourself so the slimes don't run from you. You can now run directly into them for a battle. Metal Slimes give around 1,000 experience points while Liquid Metal Slimes around 10,000 experience points. Keep in mind that Vanish's effects will fade from you and your party after a fight. Be sure to recast it to be able to run into other slimes for more experience without wasting time trying to chase them into a corner.
Use the Rank S strategy (see above) to get a Malroth, then get a Tortured Soul and a King Slime and synthesize them together to get a Wight King. Finally, synthesize them together to get a Zoma, the rank X monster.
You must have a level 10 Demon-at-Arms and Buffalogre. Go to the Scout Post and speak to the person who performs the syntheses. Choose the two monsters (one monster must be +, the other -) and you’ll be able to select the Rank S monster and synthesize it.
Every monster is ranked as follows, from worst to best: F, E, D, C, B, A, S, X. When you scout for monsters, the rank is always a single letter. However, when you synthesize monsters, the ranks are combined. F rank = 1 rank point, E rank = 11 rank points, and so on. Combining two F rank monsters would equal F +2 rank. When the rank gets to * +10, it goes to the next rank. The following are the point values for each rank:
F = 1 rp E = 11 rp D = 21 rp C = 31 rp B = 41 rp A = 51 rp S = 61 rp X = 71 rp
Note: Monsters also have species ranks for overall species strength, which is displayed in the monster logbook and is permanent.
