Alright, so as the title says I will be explaining how to make tons of Heavenly Shards pretty cheaply using Blacksmithing.
The materials you need will be: Character with maxxed out Blacksmithing/Mining (Or close to max).
Some Elementium and Obsidium ore.
Disenchanter.
Now to begin, first you need to either buy or farm some Elementium/Obsidium ore (I just buy it because i'm really lazy :/)
Once you do that, Smelt the ore that you gathered. After smelting the obsidium into bars, turn them into Folded Obsidium using Blacksmithing.
After this, you need to craft one of these items, Stormforged Shoulders or Stormforged Legguards (Doesn't matter which, they require the same mats and produce the same results).
Send the armor to your disenchanter and have them disenchant them into the Heavenly Shards. (You get a Heavenly shard EVERY time from disenchanting these).
These items require 8 Elementium bars (16 elementium ore) and 2 Folded Obsidium (8 obsidium ore). On my server Elementium ore goes for about 20g/stack so that would be 16g for the Elementium. Obsidium goes for about 30g/stack so that is about 14g for that. Add it up and it equals 30g per Heavenly shard which you can resell on the Auction House for a decent profit (It's a little server dependent).
And there you have it, an easy way to get a bunch of Heavenly Shards for a good price. Enjoy WoW players
