Lightning Rod + Call of the brotherhood (you know what im about to ask?)

so yeah... will this combo work giving me "2 rolls" and then converting?

sum 1 got idea?

Not sure what "2 rolls" you mean, but CotB converts 100% of lightning damage to cold, so Lightning Rod will deal cold damage.

yes but since the conversion should happen last and lightning rod will roll lightning damage twice (non crit)

would it give 2 "rolls" and then convert it...

I thought you were talking about this skill. That's funny how you put "you know what im about to ask?" in the title, and the question turned out to be ambiguous.

As for Ligning Rod passive notable, no, cold damage won't get lucky rolls. Conversion happens way earlier than damage rolling.
