I feel a bit silly: I have had access to [item]Gavel of Unearthed Secrets[/item] for quite some time but have ignored it. It's the Lower City exalted spell damage mace. Recall that Seal of Vengeance favors weapon speeds that approach 3.0; since SoV procs 20 times a minute, a 3.0 speed weapon would guarantee a proc each hit. 2.7 is damn close.
Though a 2.7 speed weapon procs JoW/JoL less, it will proc SoV nearly every single time. SoV is very very streaky with my 1.8 speed sword, which has a fail rate of about 30%. In fact, the DoT drops off of the mob quite frequently…it's a problem. A 2.7 speed sword has a fail rate of about 10%. It's worth some testing.
Also, since the AQ enchants are going to be accessible next content patch, I am wondering whether it would be better to put 2% threat on my gloves over 20 spell damage. Need to work the math out when I have time. Mmm threat.
Edit: I didn't notice all that huge of an increase in my TPS, considering I chanted it with +40 spell damage (never bothered doing that on my other weapons, the pattern dropped for me last week…I am cheap and hate outsourcing chants). BUT it was Friday and I was tired. I should test SoV more.
Oh, and I have a new tanking weapon which will be mentioned in the next "Weekly Update." I am feeling posty lately, might even make an entry over the weekend for once.
