I tried the following:

/castsequence [target=focus,target=none] reset=10 Seal of Righteousness,Judgement
/castsequence [target=focustarget,target=none] reset=10 Seal of Righteousness,Judgement

And I tried alternating the [target=focus...] with reset=10 and it didn't work.

Specifically it doesn't judge.

I have another idea, I'll post it if it works....
