Consult these maps for part 2:
Examine the door with Raizan equipped. You'll see all those weird slimes sticking to a door throughout the game. They are different in colors and numbers of crystals. The colors represent the power of orbs (blue = thunder, red = fire, green = wind) and the number of crystals represent the level of the orbs 1, 2, and 3. You can level up the orbs using Magic Mirror with red souls that you absorbs when killing monsters (note that the level of orbs and weapons are two different things). What you have to do to unseal it is to equip with a specific weapon depending on their color and meet required level.
kill all monsters in this area, then open the box that is half hidden behind a wood barrier.

Proceed to the next area. This courtyard has a large platform in the center. From where you appear, turn left and walk a few screens, you will see a giant axe monster with a ghost flying, kill them and enter the door he guarded (I will call it green door). The one in the middle is sealed with level-1 red crystal, so you will need a fire orb first. After you entered the door, immediately rush to save a soldier by killing 3 Zombie Soldiers, the soldier will then drop an Herb as a reward for you.
- Item: Herb
Ignore the door in front of you for now, do you see a broken wall? walk to it and use Robe Ladder to get down. Keep walking until you see a Magic Mirror and a trick box.
- Item: Power Jewel (Solution: 6th, 1st, 4th)
Do not enter the door yet, turn around and you'll see a huge wooden crate, destroy it to reveal a box containing Medicine.
- Item: Medicine
Save the game before you enter.
Boss: Osric
He is not very hard to fight, simply walking around and hit him after his last attack. He is slow so you have plenty of time to run and hit him.
After killing the boss, head into the hallway that opened when he collapsed, there is a box contains a journal file.
- File: Journal #2
Enter the iron door and walk a few steps you will see 3 jars, destroy them and examine the ground.
- Item: Fluorite
Proceed to the next door, watch a scene, then kill a new type of monster, Reynaldo. Next, pick up the fire orb. It will grand you a new weapon Enryuu, the second strongest weapon but it is also the heaviest and slow to wield.
- Equipment: Enryuu (Kouen)
Note: I recommend you prioritize enhancing orbs first in this order because they are required to progress the storyline.
- Fire orb level 2
- Thunder orb level 2
- Wind orb level 2
- Thunder orb level 3
- Wind orb level 3
- Fire orb level 3
Then, you can enhancing swords, bullets, arrows, and medicines last.
Now backtrack to Osric room, kill a bunch floating ghosts, then exit through the sealed door. This time you have to equip Enryuu to open it. Save if needed, then go to the courtyard and enter the main door with Enryuu.
Now you are in the Keep, there are 3 doors in the hall, 2 side doors on the left and one main. From your left, enter the second side door (it's a Sentry Room if see the map) you will find a Magic Mirror and a treasure box; you may also find a moth man, but ignore him for now.
