How to make projectile bypass shieldbelt?

[HQQ]

Rather than making the shieldbelt not blocking projectile anymore, can anyone tell me if there is a way to edit the xml file so that a certain type of projectile will bypass any shieldbelt?
To be specific, I want the skill Mimic of the Faceless class from Rimworld of Magic mod to bypass shieldbelts. I'd already asked in that specific thread, but it looked kinda dead.

It will probably require C# code of some sort^*.  Maybe RoMagic already does that for some of the weapons, and you can grab those hooks?

^* - maybe unless there's some way you can convince the game it's really a melee weapon??
