You need the Password from Yenani, a Gwani, before you can enter the Skullcrusher Mountains.
City of Chaos
Upon entering at (2N, 2E) you will find 5 Pedestal and and some Rune is on it and some is lying around. Check the Plaque to check which Rune belongs to which Pedestal (for once the Translation Spell is not useful). In the Corpse is a Scroll in Serpent Language, so cast Translation Spell and read it. Start clicking on Rune (I) on westmost Pedestal, then (S) Middle Pedestal, (I) topmost Pedestal, (G) South Pedestal and lastly (I) the eastmost Pedestal. If you are doing it right, then the Avatar will say the Password and the Gate will open.
Go East into a House. Go North in a sort of a Museum. Read the Book to see what Vasculio stole from the Mages in Moonshade. Drop the Black Sword on Ground and click on Flux Analyzer to restore the Power of the Black Sword. You should also take Philanderer's Friend with you. It will be necessary later on. The Gwani Horn is in a Energy Field and you don't have the Dispell Field Spell yet, so remember it when you come back later.
Go in Prison and a Skeleton will ask to aid him, so unlock the Door with Magic and as thank he will attack you. Slay him and check the Corpse in Cell. It has 2 Serpent Tooth. The Serpent Tooth will lead you to Great Northern Forest and Fawn. The Book tell you of the Destiny of the Corpse names Maleccio. Now read the Scroll in Coffin-Room. There are 4 possiblity in dealing with Vasculio, depending if you have the Magebane Sword or not:
- You don't have the Magebane and said yes to the Deal, but your Companions won't agree to sacrifice and so he will attack you immediately.
- You don't have the Magebane and said no to the Deal. He will attack you immediately.
- You have the Magebane and said yes to the Deal. You will receive the Mass Death Scroll and the Magebane Sword will disappear and he will attack you immediately.
- You have the Magebane and said no to the Deal. He will attack you immediately.
Don't bother to deal the Magebane Sword for Mass Death Scroll. The Magebane Sword is unique and you can buy Mass Death from Ensorcio and Mortegro. Take the Key from the Corpse. The Bedroom southwest is filled with evil Gwani unlike the friendly Gwani outside, so you can slay them. Go South of Vasculio's House.
The Ghost there is not evil and will drop a Book to the Ground. The Book is a Hint to where to find Magebane Sword. There is also a Translation Scoll in Library. West of Vasculio's House is a Theather with 4 friendly Ghosts. In the Restaurant is also a friendly Ghost. East of the Theather is Vasculio's Lab. The Book there tell of Vasculio's Experiments. South of it is the Warehouse, but all Chests, Crates and Barrels are empty, but in Southwest Corner is a hidden Powder Keg. East of the Warehouse is the Armory. In the locked Chests are also mass of Boomerangs and Clubs.
Go East over the Bridge to the House you see. It has 3 Gems, 1 Gold Bar and 2 Powder Kegs. Go North in the next Building. There is a Scroll on Pedestal and some Fire Pillars and 2 Automatons guarding a massive Gold Double Door which cannot be destroyed, not even with Powder Keg. Going North to find one more Powder keg under the Debris. Continue North and check the Corpse Pile near the Bridge for a Magic Gauntlets. In Northwest is the Serpent Gate and another massive Gold Door. Rembember it as you will come back later in Game and you need a Powder Keg to destroy it (There are plenty Powder Kegs to find in this Mountain). Go East to a small Door. Unlock it with Key from Vasculio. You are now out of Skullcrasher.
Go to the Temple of Emotion at (21N, 50E) and get the Mass Cure Scroll and look into Moon's Eye to see what Batlin is planning. At (39N, 96E) is the Entrance to Spinebreaker Mountains where Batlin wait for you.
At (67N, 123E) is a Cave which is apparently a Deadend, but it has a Secret Path to the East. It leads into the City of Order and is a Shortcut.
At (50N, 40E) is a Hidden Entrance to Silverpate Treasure. Check the Map you found in Underground Cave of Inn of the Sleeping Bull to see which Path must be taken.
