-Go to Thjorgard Training Hall. Fall down the chandelier and go west. After that, break the crate where the Black Chest is located and get the artifact. Leave through the door with all the lizards and return. Another powerful artifact will be there every time.
-In the Dragon's Lair in Lindisfarne, there are two Black Chests behind the King Dragon. Run past him and grab the chests without killing him. Leave and they will be refilled again if you return. The Dragon King hits hard. It is recommended that you buff your party with spells and saving every time before you go in. This is faster than the Training Hall method, because there are two chests and they are easier to find.
First, enter the house through the broken window after climbing the stairs. Open the door and go forward. Ignore the sleeping guards. Open door directly in front Keep on going forward until you see the baron, then run right, then forward. Next, turn left and jump down on top of the bookshelf. Once there, you are invincible unless you go down or duck. Use your ranged attacks on the baron and all his guards that are in sight. They have no ranged weapons and you can keep attacking the baron until he dies. This may take a minimum five minutes, as you are still relatively weak when compared to him. After killing all the alarmed guards, go down and get all the goods (sacks). Finally, exit this room through the door to the left of the bookshelf. Shoot the single guard there and kill him. Escape the house through the front door.
Do the following when in Guberland and you are stuck with a mission to become mercenaries and must relieve the late guard. If you have already killed him and he disappeared, jump into the ocean and swim to the right until you cannot go any farther. A live guard should be stuck in the corner, walking nowhere. Kill him, use the town portal, and return outside. He should be back at the dock. Note: Occasionally he has very good armor; kill him as much as you can.
-After entering the locked door on the Isle of Ashes, open the chest to the right, just inside the door. Do not click on the book; this will take you to the next part of the game. Instead, go back through the door and enter the Verhoffin Ruins. Do not enter the doors. You are not strong enough to kill the skeletons in there. While in here, go down the hall and around the corner to the end and open the chest. Take everything and leave, then go back to the now opened door and look at the chest. It should now be closed. Re-open it and take everything. Go back to the ruins, leave ruins, go back to chest, and the chest will be closed again. Keep going backwards and forwards collecting items from same chest. Note: This was done with the v1.2 patch of the game.
-There are two chests in the area where the old woman will give you the Dragonfly quest. One is at the end of the Dragonfly Cave and the other is inside the keep (door which could not open). Enter the ruin castle and exit to get to the loading screen. Those chests will now be reset and filled with items, spells, skills, and items. This can be repeated as many times as possible. Note: This was done with v1.0 of the game.
