So here's the list of Elf Quest Pack Artifacts, for any who needs it. Obviously if I missed something, please let me know!
*Possible Spoilers*
Elixir of Life (again, from GS) - Quest 1
*Elven Bracers - Reward for Completing Quest 1
Spell Scroll (Treasure Without Doom) - Quests 4 & 6
Elven Boots - Quest 5
Ancient Staff - Quest 6
Sky Orb - Quest 7
Bone Wand - Quest 8
Elven Bow of Vincidation - Quest 10
* Only in Phoenix's revised version of the EQP, that is. In the original you get the "Elven Chain Mail" instead, which has no card, and is the same as Borin's Armor, but it's chain mail. The Elven Bracers, like the BQP's Armband of Ice, is never actually present as an item you can get in any official quest! (check out my fixes for the Phoenix quests here)
