Can anyone confirm whether the 25% of Hits converted to crits from Disciplined Strikes works for spells?

 

I'm testing with some missile spells and can't seem to see anything in the log to indicate it's procing.

 

Also I noticed Minolettas Minor Missiles have no accuracy. This implies they always hit but likewise can never crit?

It should do as it's part of the Inspiration and not a separate, melee specific buff.
