I would think yes? I don’t really know but I’m sure you can test it yourself in about 3 seconds. Will tell you that you can attach both crystal weapon and imbued weapon onto an overload light attack, if that matters to ya.
Just tested this on a bow/bow sorc and the answer is yes, overload light attacks do contribute to bound armament stacks just like regular light attacks do.
I can confirm overload works in contributing to bound armaments, it also receives the 10% buff to light attack damage, also crystal weapon works with overload. I.E (curse, crystal weapon, overload light attack, force pulse) will all hit simultaneously
