Raw materials for crafting from scratch:

200 Motes of Air = 20 Primal Air
200 Motes of Water = 20 Primal Air
120 Adamantite Ore = 60 Adamantite Bar = 6 Hardened Adamantite Bar
24 Khorium Ore = 12 Khorium Bar

<Alternative: 80 Badges of Justice> = 8 Primal Nether
100 Motes of Mana = 10 Primal Mana
1 Thunder (Already made from the above set of materials)*

<Alternative: 75 Badges of Justice> = 5 Nether Vortexes
1 Deep Thunder (Already made from the above set of materials)*

*Even though its not a raw material, I add it in the list because it will be consumed when you craft the weapon. This is so that Blizzard could give you the feel that you are upgrading your weapon.

Tier 3 version of Thunder, the level 70 crafted epic master hammersmith twohander. The items required for it are a confirmed drop in Serpentshrine Cavern (Pre-Hydross trash).

Nether Vortex's drop from all trash in SSC and TK, and drop quite plentyful. At least, we're having vortex's go to offspec loot and alts and such, so if your guild does SSC or TK, these shouldn't be too hard to come by.
