This is a very easy way to earn Tradeskill XP (experience) and Tradeskill Alternate Advancement XP if you are well below the level 70. Once you are at level 70, the XP is decent, but not quite as good as doing tradeskill rush orders closer to your level. If you do not turn all the sub-quests into the goblins inside, you can keep crafting presents for extra XP.
As a precaution, do not turn in the quests individually; if to need to log off or switch zones, completed quests will be reset and will have to be redone.
All necessary resources are available next to the crafting stations. Quest-givers supply you with a scribable recipe and a goblin in the zone sells fuel.
Watch the ice! It's slippery, and if you fall to the lower levels there is no escape so you will have to teleport!
If the recipes are red to you, the crafting stations can kill you if you miss any reaction arts, so pay attention!
