The Catacombs (Apprentice Mode)
Red Cave 1
Go through the left entrance.
Red Shaft 1
Go through the right entrance.
Den
Try to Go forward and you'll be accosted by twin gargoyles! They're pushovers in this mode, and easily spooked. You can Use Flumoris to startle them, or Use your Dirk or Sword to frighten them off. Go through the center entrance.
Red Tunnel 1
Open the Threadbare Sack on the ground to find the Timeworn Scroll, Tablet, and a Blue Crystal. The Timeworn Scroll is some lore, and mentions the fact that there are some easter eggs from the original Shadowgate game down here. Only two of which you can find in Apprentice Difficulty, and I'm skipping past one with my directions here so you won't come across it unless you explore on your own. To continue on with the quest, Go through the right entrance.
Red Cave 2
Go down the ladder.
Red Shaft 2
Go through the entrance.
Rendezvous
There's a gong in here that you can hit with the Mallet you picked up in the Music Room, but to my knowledge, this does nothing except reference the original game. For now, at least. Go through the right entrance
Red Cavern 3
Go through the only entrance in here.
Red Shaft 3
Go up the ladder.
Red Shaft 4
Go through the passage.
Red Cave 3
Go through the passage. Apprentice is a very exciting time to be in the Catacombs.
Red Mine
Go through the passage.
Red Tunnel 2
Go through the right passage.
Chasm
There's a small rock pillar just before the chasm proper, Go to that stone to reach the Crystal Puzzle.
Rock Table
You need to place certain colored crystals in certain slots to solve this. In Apprentice Difficulty, all the crystals you need are already in the rock table, but none of them are in the correct spots except for one red one. You can start by Taking all of the crystals and then placing them, or just Use the ones already out on the correct slot to move it.
The goal is to match the crystals with the peaks depicted on the mural in the Ornate Chamber. Start by Using the Red Crystals on all of the slots in Row 4. Then Use Blue Crystals on the last three slots on the right of Row 3. Use the White Crystal in the third hole from the right in Row 2, and finally Use the Black Crystal in the third hole from the right in Row 1. Use the Crysalys spell on the Rock Table to complete the puzzle.
Chasm
A fancy bridge of light appears across the chasm, which is something I really Dig. Go across it and through the doorway on the other side.
Yellow Cavern
Go through the passage.
Yellow Cave
Go through the passage.
Yellow Tunnel
Go through the passage.
Skull Door
Use the Invokan spell on the obelisk to summon Lakmir for a final time. He reveals that the Staff of Ages requires an empowerment involving a great sacrifice in order to be fully formed. Use the Silver Orb on Lakmir to capture his spirit within. Use the Stave with the Golden Thorn, then Use that combo on the Silver Orb to create the Staff of Ages. Note that the Silver Orb won't combine with the Stave unless you've first captured Lakmir's power.
Now we just need to open up the door. If you looked at the Tablet you picked up earlier, you'll see that it has a picture of a hand, something that looks like the Bladed Sun, and then four vertical lines. Following those directions, Use the Bladed Sun on the recess located on the ring finger (fourth finger across from the left), then Use the Platinum Horn on Thyself. Assuming the Bladed Sun was properly placed, the door will open and allow you to Go through to the final battle.
Summoning Chamber
The great Behemoth has already been summoned. Are we too late?! The Warlock Lord will summon three glowing orbs that circle him. In order to end Talimar's evil machinations, Use the Staff of Ages on any one of the three orbs to break his spell.
Now just Enjoy the ending!
