Secrets

 * 1) Open the yellow door at the castle entrance (which is in the northeast part of the room with the Ethereal Crossbow) and on the steps leading to the next door, shoot at the wall where the vines are to open up a cave with an Enchanted Shield. (sector 279)
 * 2) After crossing the bridge to the blue door, open it and go along the next hallway. When it bends, look southeast and shoot at the rock wall to reveal more of the cave. Make a jump across the column to this ledge and follow the cave all the way until you reach a Tome of Power. (sector 1445)
 * 3) Along the U-shaped path at the northwest part of the main map, once you reach the yellow door, pres on the wall left of the entrance to reveal a switch. This switch reveals a part of the cave on your left, where you can find a Silver Shield and a Tome of Power. Look out for Nitrogolems when you leave. (sector 1624)
 * 4) At the southeast section of the map with the pillars, you need to jump across them to reach a switch, which will open the bars to reach the far southeast section where the exit is located. Once you step onto the platform with the switch, you will also light up a certain wall. To reach this wall, go back the way you came across the pillars and take the lift back up. Head into the next small hall and turn north. You will find the lit wall here; press on it and return to the lift room to find a passage next to the lift. Take this passage to find an Enchanted Shield. (sector 1845)
 * 5) At the section of the map in the southeast with all the pillars to jump across, look for a Morph Ovum to the northwest. Find a pillar where you can jump to the grotto where the Morph Ovum is to collect it and claim the secret. (sector 1913)
 * 6) In the final arena, open the northwest wall to find two Energy Orbs and two Inferno Orbs. (sector 1981)
 * 7) After getting the yellow key, return to the waterfall area from before to find a cave at the southwest corner. Enter this cave and shoot the wall behind the Bag of Holding to find a passage. Go across the blocks over the lava to get a Phoenix Rod. (sector 2021)
