A Soul's Bane

Walkthrough

 * Go east of Varrock, through the gate by the earth altar and just south of there, speak to Launa. Alternatively, take a glider to digsite.
 * Take a Rope and use it on the rift and then climb down into the rift. There are several "rooms" which you need to get through to complete the quest.

Rage

 * When you enter this room you should see a weapons rack, unwield your own weapon and select any of the weapons from the rack and wield it.
 * There are four types of monster in this room, and each is killed with a specific weapon.
 * Sword - kills unicorn
 * Spear - kills bear
 * Mace - kills rat
 * Battleaxe - kills goblin
 * Kill monsters to raise your rage level - there will be a bar showing at the top of the screen. When your rage level reaches maximum, you will be able to move on to the next room.
 * Unfortunately, it is not possible to level up your strength, defense and/or attack fighting these angry animals as you will not receive any experience points.

Fear

 * In this room you have to search the dark holes. In some of them you will find Fear reapers.  You have to kill around 5 or 6 before you may proceed to the next room.

Confusion

 * In this room you have to kill Confusion beasts - some are illusions and you will not inflict any damage on these, they will just disappear after a while. The beasts may poison you, but just keep attacking them until all the doors in the room disappear except for one.

Hopelessness

 * In this room you'll find 4 Hopeless creatures. They need to be killed 3 times each to make them die.  Once you've killed them all the bridge of hope will appear.

Tolna

 * After crossing the bridge, you'll see a short cut-scene, and you then get to fight Tolna, a 3-headed beast. Kill each head, they may also poison you, and Tolna will become human again.
 * Talk to Tolna and he will take you back to the surface and reward you.

Reward

 * 1 Quest Point
 * 500 Defence experience
 * 500 Hitpoints experience
 * 500 Coins
 * Access to the Dungeon of Tolna
