P.S.

Since you are making such a clamor about the Sireth on a Paladin/Monk build in the other thread you should probably be made aware that:
(a) Sacred Defender locks you out of Rage-like effects
(b) you will not get Improved Sacred Defense bonuses unless you are wielding a shield, medium armor, or heavy armor

Therefore, Sacred Defense on an in-stance staff-wielding Monk is pointless; at best you'll get +10 PRR and +50% Threat. You're better off twisting in Primal Scream.
