So I have (or unfortunately "had") an Omnissiah Axe.
In our last game, we came across what we perceived to be a Necron Pariah. During the battle, it completely destroyed my axe through the use of some form of "acid" (though meta-game knowledge pointed to something similar to scarabs).
In the Dark Heresy rules, once I repair/replace my axe, is there any way I can upgrade it in an attempt to avoid this happening again?
The only other thing I found was the Lathe Blade upgrade (DH: Inquistors HB p.147), though that only talks about increasing the physical quality of the weapon, so I'm not sure how useful that would be.
