You get Formula: Enchant Gloves - Threat from The Sha'tar at Exalted in Shattrath City; older guides also note it used to drop from Emperor Vek'nilash in the Temple of Ahn'Qiraj before patch 2.2. The enchant itself increases threat by 2% and requires Enchanting 300.

Where to get it

  • Modern source: buy the formula from The Sha'tar once you are Exalted.
  • Older/legacy source: it was originally a drop from Emperor Vek'nilash in AQ40.
  • What it does: permanently enchants gloves to increase threat from all attacks and spells by 2%.

Reagents

  • 4x Small Prismatic Shard
  • 2x Greater Planar Essence
  • 8x Primal Life

Quick note

If you’re asking about the formula item versus the enchant effect , the buyable formula is the current easiest route, while the AQ40 drop is the old-school source.
