Save and quit the game. Find the filenames "rag_save.000" and "sdata.000" (the first time you saved the game) and copy them to another folder. When your character perishes, exit the game, locate these files, and copy them back to the Ragnarok folder.

Hints
Chaos: Artifact

You need to have the Dimension Travel power and a grappling hook. Go to Chaos and drink a Potion Of Depredation. When you see an amulet or armor, place your pointer on it as a marker. Try to go near to that place and wait for the time until the armor or the amulet appears.

Crypt: Artifact

From ten meters underground, find the stairs leading down to twenty meters underground. Go down to the stairs and read a Scroll Of Cartography. You will see green stairs trapped in a wall. Dig to make a path and go down the stairs. When you enter a room and encounter some traps, the artifact is somewhere in that area.

Slaeter's Sea: Artifact

Read a Scroll Of Cartography and drink a Potion Of Depredation. When you see an amulet or armor, place your pointer on it as a marker. Go near the item and read a Scroll Of Lava Strike to get it.

Wastelands: Artifact

You need to have the Terraforming and Dimension Travel powers. Go to Wastelands and read a Scroll Of Cartography. Go near the volcano and terraform it into ground or another terrain to cancel its eruption. You can now find the artifact without haste.

Defeating Gymir

Go to Jotenheim and find Gymir's small castle. Terraform the door into water. Start attacking him by using throwing weapons. He is not affected by wands. Alternately, summon a magical being to kill him in one strike.

Defeating Vidur

Use a Wand Of Death at him. Be careful, because a Wand Of Death has a long range.

Resistance to petrification

Find a Wand Of Wishing, use it, and wish for a "Dead Hel Dragon". Eat this and you will have resistance to petrification.
