Voidveil seemingly isn't converting magical damage taken into Void energy. Tested with two characters who have Void Assassin as their subclass, both wearing unarmored torsos made out of cloth material. One being a snakescale ninja armor, the other being a breezecloth ninja armor. One could assume if the energy from damage isn't working, the damage reduction also isn't working, but I've yet to try this on a character with VA as their main class.

I put these two characters against one another and dealt magical damage. The only increase in void energy was from Radiation - 3 per round.

Not sure if this'll help, but here's a debug log of a Warp Strike against a VA.
