heirloom items and locks

fist off if you have the badges and are starting off i think you should get the tattered dreadmist mantle or robes first they cost 40 emblems each then i would suggest getting the dignified headmasters charge costing 65 emblems and last 2 discerning eye of the beast costing 50 emblems each if you get them all at once it will cost you 245 emblems total.
now you can get the swift hand of justice times 2 ore one of each but i find the spell power is more helpful then the haste is.
a great site to get an idea on how these items scale via lvl is.
