Demon Slayer

The Trials of Silverlight
Start by talking to Grüfeld Bach in the Saradomin church north of the Varrock Museum. He will tell you that the demon Delrith is being summoned and instruct you to enter the crypt under the church. Enter the trapdoor on the north side of the church.

You will see three spirits, talk to them, they will tell you you have to pass three tests to be worthy of Silverlight.

Body
In the west room, you will need to kill 10 skeletons. Pillars can be used by low-level players to decrease the amount of damage taken. As they will all attack at the same time, using ranged.

Faith
In the northern room you must walk along an invisible path guided by the spirit, when doing this trial only take one step at a time then wait for the spirit to tell you which direction to walk. When you are done, walk back over the chasm ( you dont need to walk over the path this time).

Mind
Answer a series of simple questions pertaining to the quest.
 * 1) I seek the Silverlight.
 * 2) A sword that slays demons.
 * 3) A powerful demon threatens Varrock.
 * 4) Delrith.
 * 5) Grüfeld Bach.

Claiming Silverlight
Talk to the spirits in the center of the room again, they will congratulate you and give you access to Silverlight.

Through the Catacombs
Talk to Grüfeld Bach again, and he will tell you to go to the Zamorak Church in South-East Varrock near the Rune Shop. Enter the trap door, and fight your way to the middle. Low level Zamorak Monks will be in the way, as you kill them a barrier opens allowing you to pass into the next room. This is short and easy.

Fighting Delrith
You will come to a big room where Denath is, then he summons Delrith and leaves. Grüfeld will protect you from his inital blast, and all the "Prepare to be incinerated!" blasts after that. Make sure that when the barrier appears that you are inside it otherwise you will be reduced to one lifepoint. If you are caught off-guard and and delrith is about to do the "Prepare to be incinerated!" blast then quickly turn "Protect From Magic" in your prayer book on. (Requires Level 37 Prayer)

The demon can ONLY be fought with either Silverlight or Darklight (If a player has acquired Darklight before the remake of the Demon Slayer quest.) as your main hand weapon, if your offhand weapon delivers the killing blow, Delrith will still die, so go ahead and slay him while wielding it.

After the fight the room will collapse, and you and Grüfeld will pop up where you started in the church.

Congratulations, Quest Complete!

Reward

 * 3 Quest Points.
 * The sword Silverlight. If you lose Silverlight, you can get a new one from Grüfeld Bach. You can also sell it to the Wise Old Man in Draynor Village for 80 coins. The sword, bearing powerful magical properties, can be kept by the player forever after the quest and used as many times as desired, especially strong against demon-type characters.
 * If you are a member, you can talk to Historian Minas at the Varrock Museum to receive 5 Kudos.
 * 3 xp lamps worth 100xp each
 * 2 extra spins on the Squeal of Fortune

Required for completing
Completion of Demon Slayer is required for the following:
 * Defender of Varrock
 * Recipe for Disaster/Freeing the Lumbridge Sage
 * Shadow of the Storm

Trivia

 * The Spirit of the Mind has several answers that may be considered 'subjective' (Silverlight as a musical troupe, the adventurer actually likes visiting catacombs), but will admit that they are not the correct answers it is looking for.
 * If you destroy the Silverlight obtained during the quest as a free player that has Shadow of the Storm completed, the quest becomes impossible to complete, as you will only be given Darklight back, which cannot be equipped on free worlds.
