Go to Runinshaven island, the island south of Ljasdal with the cult, and find the cave that can be found by traveling. On the first floor of the cave is a donation bowl. Enter 999999 and you will receive money instead of donating it.
In the central-northern part of Prem there is a hidden cavern at the end of a short road. When you step on the correct location, a screen with the door will appear. Each time you leave the cavern, you will earn about 400 experience points. Repeatedly enter and leave the cavern to gain several levels quickly. Note: Make sure you have high energy to deal with the occasional cave-ins.
To complete the game you need to find the following items. Locate seven parts of the treasure map to find the Blade of Destiny and the attack plan from the Orcs, which is found in the orcish cave between Skelellen and Phexcaer. With the attack plan, you can find the Orc camp between Phexcar and the Lonely Lake where the Anchorite lives. You will still have enough time to find eight pieces of the map. Finding the ninth part depends on a random encounter and it cannot always be discovered. When you get the message that something on the map can be decrypted, you will have enough parts to find Hyggelik and Grimring. You must get to the Or camp and defeat the Orc Champion no later than two years and ten months after starting the game, and the date when the Orcs will raid the land is the 27th Peraine, 17 Hal. When you have Grimring and the attack plan, you can afford to do other things, but always keep note of the calender.
