After you completed all 3 Part-Dungeon you will learn the Fly-Spell on the World and a bit later you will meet Bronakh himself. He tells you to go Island of Lamant to Hall of Rage. It is in the Mountain east from Dark Magi Tower.
Pull Flowerpot and move it East beyond Water-passage to block a Lighting. In the Alcove beyond Flowerpot you will find 2 Potions of Detect Illusion. Go East and pull Lever and go North but beware of Lighting coming from the North. Go in second Alcove left to get teleported to 2. Kill 3 Spiders and step on X-Field to leave this Place. Continue North to get teleported to 3. Kill 3 Ghosts and step on X-Field to get out of this Place. Cast "Detect Illusionary Wall" and "Walk on Fire"-Spell and go North through Illusion-Wall. Continue North and go right. Step on both X-field and fight 1 Spider and 1 Ghost. Try to go through the middle and open the Middle Door. Kill Spider and Pluder Chest behind Illusion-Wall for 5 Extra Healing Potions, 3 Cheeses, 1 Bread, 1 Berserker Sword, and 1 Potion of Detect Illusion.
Leave this Place and go North. Jump across Trap-Corridor and go right. Move Flower-plant a Step forward then move it back. Push another Flowerpot to East all along, then push Flowerpot to South and pull Lever. Now push another Flowerpot South and pull North Flowerpot a step West and South. Push another Lever. Now go West and push Flowerpot North and another Flowerpot East. Now push next Flowerpot North and pull it East. Pull another Flowerpot also East. Go South and West. Push Flowerpot North and push another Pot East. Kill an invisible Ghost for an Opal Key. Unlock Door with it. Continue North and West. Go either Water-Passage or Fire-Passage.
Hint: Beware Anti Magic- and 360 Degree Turn-Field.
Pull Lever and step on X-Field one after another. Climb down the Hole. Go South, West, North and West. The Crossing is a Spinner so try to go South. In South Room is a Chest which contains 1 Turquoise Key, 1 Jail Key, 1 Flame Blade, 1 Plate Armor, 1 Potion of Detect Illusion, 1 Ring of Mighty Attack, 1 Necklace of Protection, 1 Ring of Protection. Now that is a Awesome Treasure to find. Go back to Spinner and go either North or West. Don't matter. Cast "Detect Illusionary Walls"-Spell or use Potion. Move Flowerpot a step to North then all the Way West to block Fireball. Go back and go North, West and North again. Burn down all Spider-webs with "Firepath"-Spell.
Help: It seems there exists a Pressure Plate in Spider-web Area but what is the use of it? Please advise me.
It will take some time to move to Spider. Kill it and take Golden Key from it. Go back all the way and Unlock Door with Golden Key. Jump forward to avoid Lighting. Unlock next Door with Turquoise Key. Continue forward to get teleported to 4. Now go South East and cast "Swimming"-Spell and go north. Unlock Jail-Door with Jail Key and kill last Ghost. Pull Flowerpot west and go North behind Illusions-Wall and exit this Dungeon.
Hint: try to get at least 220'000 Exp for both Fighter and 190'000 for both Mage.
After you have completed this Dungeon, Bronakh will meet you again and bring you to Bronakh Rage (the Volcano) automatically.
