Those boots are worse than the Ra-den ones. Gemming for bonuses of course.
Dreadrunner Sabatons:
Agi: 828
Secondaries: 841
Treads of the Sanguine Volley:
Agi:788
Secondaries: 1019
Anyone in their right mind knows that 178 secondaries is well worth 40 agi, considering it is ~.33 secondary per point of agi.
The BoA bow is not even close to the gun
Voice of the Quilen:
Agi:1279
Secondaries:1113
Hellscream's Warbow:
Agi:1179
Secondaries:979
Clearly not even close.
Not sure if this is true, will have to test tomorrow.
Just checked the prismatic socket is definitely giving stats in proving grounds.
