Instruments of Virtue and channeling spells

Hey,

How does Instruments of Virtue interact with channeling spells regarding the "each non-instant spell you've cast" ?
Does channeling a spell count as one whatever the channeling duration ?
Does each stage count as one for some reason ?
Does channeling stop'n'go in quick successions count as 3+ ?
Any other possibility I overlooked ?

Thanks for your help !

Instruments of Virtue doesn't work with triggered spells, no matter how you trigger them. They don't count as you casting the spell.

Um, I get that triggered spells aren't cast and so don't count, but that's not my point, unless channeling spells count as triggered for some reason ?

Also I'm not planning on using CwC, if that's the reason of your answer. I plan to play Brutus' STR stack and wonder whether Scorching Ray is a viable option or not.

Ah, in that case yes, it should sort of work. Only the initial startup counts as a cast though, so you have to do a start/stop routine to ramp up Instruments' effect. I'm guessing its the Exposure you're after from Scorching Ray, and if that's the case you'd be better off doing 3 quick casts of Wave of Conviction. The exposure won't be as strong, but getting it and maintaining it that way while also maximizing Instruments is far more efficient.

My issue exactly. Thanks for your answer !
