After accepting the quest, speak to Pinchy again to be teleported to the Elfin Wonderland.
Once you're inside the zone, check your inventory immediately for two items:
A Frostfell Elf Hat -- without it on your run speed is slowed by 70%. Equip it in your normal head slot.
A Elfin Snowball Satchel, which you can hotkey from your inventory onto a hotkey bar. Using this item will deal 50% of a mob's total health to it every shot, killing them in 2 hits.
The zone is plagued with many mobs which scale to your level. If you are having trouble fighting here then we recommend using the snowball satchel to dispose of them quickly when they are encountered. These mobs also do not see through invis/sneak if you wish to use that method to quickly bypass them.
The object is to gather elfin magic--red, green, yellow, purple and silver. The magic is inside bottles will have a large aura of magic around them. Follow the candy cane trail to the southwest and keep going until you find all of the bottles. If you are using invis or sneak it will drop whenever you click on a bottle.
Silver Elfin magic, down a tunnel: -259, -10, -162
Purple Elfin magic, guarded by an ice wyrm: -207, 1, -320
Yellow Elfin magic, guarded by an ice terror: -208, 13, -350
Red Elfin Magic, guarded by an ice shard: -219, 1, -394
Green Elfin Magic, guarded by an ice golem: -253, -0.45, -415
After gathering all of the magic you must confront Grimagus.
In the east part of the zone you will find Lord Bowsprite at -470,-1,-358 . Speak to him.
Lord Bowsprite makes a rainbow bridge for you to cross. Go over it.
