Mourning's Ends Part II

Walkthrough
After starting, put on your full mourner clothes and remove all of your other worn items. Make sure that you have a chisel with you. Bring lots of food and a teleport, but leave one inventory space open. Go to the basement of the Mourner HQ in Ardougne and talk to the Head Mourner.

He will give you a key to the nearby tunnels that they dug to the Temple of Light. He will ask you to find the digging team, a group of slaves and Mourners that have high enough slayer skills to defeat the beasts in the area. Go into the tunnel. You will see level 182 Dark Beasts. They require level 90 slayer to kill, can hit up to 18, and guard a rune rock. Run past them to reach the temple entrance. You'll see a cutscene. Search the corpses of the digging team to get a diary. Read it.

Return to Arianwyn to learn about a blackened crystal in the Temple of Light. Go to where you found the digging team. You'll see level 74 Shadows all over the place. They only have 15hp, but they can hit very accurately, are hard to hit, and can hit up to 13. They're very annoying. To get to the black crystal, from the entrance of the temple, go west. Climb up the stairs. Then go west and as far south as you can go. Go up the ladder. Then go north, west a bit, north again and down the stairs. Go up the next set of stairs and walk east, then south to the crystal. Use a chisel on it to break off a piece. Go back to Arianwyn.

He will summon Eluned, who will enchant the black crystal in your inventory. Put this in your bank, as you don't need it now.

Blue door
Go back to the Temple of Light with lots of food. Go up the stairs, then go east to the crystal collector. Pull the lever and collect the items inside. You'll get a yellow crystal and some mirrors. You need to unlock the blue door with a yellow beam of light. The pillar next to the crystal collector has a beam of light flowing through it.


 * Put a mirror in it and reflect the light north.
 * Walk north to the next pillar. Add a mirror and reflect the light west.
 * Go south to the next pillar. Use your yellow crystal on it to dye the light yellow.
 * Go south and put a mirror in the pillar. Reflect the light east.
 * This part is very frusturating. You must climb across several handholds, but each one can be failed, so you have a very good chance of falling off.  Falling will hit 5 damage on you, and tons of Shadows will attack you.  Go back up the stairs and try again until you make it.
 * Pass through the blue door and open the chest.
