OK so here's how it goes

1) get a Libram of Voracity drop (or easy to pick up from AH)
2) Wipper roots are from the felwood gatherer chain - druid in Felwood gives the quest out - great details here on Thott
3) Crystal Force - use pylons in Ungoro to convert Blue & green crystals to Crystal Force
4) Black diamonds are drops / AH items again

gather all mats and take to the NPC in north of Burnning Stepes - he gives out the libram. It works like an enchant so use on your own gear or on others via the 'will not be traded' slot

Sold plenty for good gold 65 - 95 is going rate on Doomhammer

You have to take this to the Blood Elf at Flame Crest, Burning Steppes along with:

- 30 gold
- a Black Diamond (found in BRD)
- 4 Whipper Root Tubers (found in Felwood, but can only be collected after the plant is cleansed with a Cenarion Salve)
- 4 Crystal Force (found in Un'Goro Crater, you can create these from 10 green and 10 blue power crystals at the Eastern Pylon)

As a reward you can choose from items that can permanently enchant your head/legs item with 8 to str/agi/sta/int/spi.

Good to know info:
Unlike the Aldor or Scryer enchanting items. Which bind to you when you get them and then bind the item you use it on to you also.

Only the Arcanum binds to you. Using the Arcanum on an item does not bind the item to you.

So... +8 stam on a twink head piece is something to think about.

This is actually quite useful for a paladin. Consider what the +8 Int does for us. First, +8 Int. Assuming at 60 the paladin formula for spell crit is:

[INT/29.5?]%

This gives us .27% crit chance for 8 Int.

Now, also assume that paladins have Divine Intellect, and Blessing of Kings, that increases the 8 int to about 9.6 (or 9.68, however, they do the math) int. Assuming they round up, that's 10 int.

Compare this to the ZG enchant, which give us 10 Stamina, 24 healing, and 7 defense. Assuming at this point that defense is all but useless for a current end-game raiding paladin, it comes down to +healing and stamina and more mana and spell crit.

With two enchants, you have the following totals:

ZG: 48 +healing, 200 health
LIbram: 20 Int (assuming BoK and DI talent), which gives us .54% spell crit, ~300 mana

Considering the limited number of ZG enchants you can get these days, +8 int doesn't look that bad.
