Currently running a thf cleric, similar to Axel's THF build but 1fighter/1fvs/18 cleric pdk. Not using an imbue, falconry for hit/damage.
As I'm using haste boost from vistani 5 piece prowess is a no brainer (using 2 melee power filigrees, one in artifact, one in weapon).
Raid Filigrees I'm using 2x Blood feast/One Against Many for the melee power, 2 x Celerity/Vigilence (+2 Wis), 2 x Bravery Througout/Shattered Device (+6 PRR).
I then slot another two shattered device filigree's for the 4 set bonus and then a Celerity +dodge/dodge cap filigree to round it off for the perma haste bonus from the 3 piece celerity set.
