Reforging allows you to modify the secondary stats on your gear. Use this guide to determine the best strategy for reforging your stats so that you can optimize the performance of your Shadow Priest.
Intellect > 15% Spell Hit (Hit | Spirit) > Haste (Breakpoint) > Crit = Mastery > Haste (Past Breakpoint)
1. Check Spell Hit for 15%
If you are not at or above 15% (5100 Rating), on any gear without Hit, reforge the weakest stat (see stat priority) into Spirit or Hit until you are at or slightly above 15%.
2. Optimize Secondary Stats
On any gear without Haste, reforge the weakest stat (see priority) into Haste until you reach the Haste breakpoint (8,085 Rating or 10,124 Rating). After reaching the Haste breakpoint, reforge for Mastery or Crit as available.
