Suggestions for Infernal Blow Templar

So my friends did a fun random selection of class and primary skill for the new league and I pulled Infernal Blow Templar.

I haven't played IB for years and haven't had a Templar in a long time as well,

I can't find a build with this combination that isn't at least 2 years old.

so I'm interested in any suggestions for a way to go with it,

Crit Inquisitor?

Purity Guardian?


Thanks
