Cannith Challenge ingredients

What to run for ingredients

 * Epic version ingredients are only used for the Tier 2/3 upgrades for Level 20 version items. They can only be obtained by running Epic version challenges.
 * Some ingredients are always awarded, even if XP gained is zero. At level, you get 100% normal score (and thus rewards) for any given challenge. You get less when you are above the quest's level, to a minimum of 10% for being 5 or more levels over. If you are on a 20 running a challenge that only goes up to level 15, you get identical score penalties (and thus rewards penalties as they are a direct percentage of your score) going in on level 15 or level 4.
 * As of Update 12 Patch 1, ingredients can be exchanged. See here for details.
