That could be a good house rule to use. Each step up in quality gives a 25% bonus to the weapon surviving. So a poor quality weapon will break every time, but a best quality only has a 25% chance. If the weapon is blessed and weilded by a faithful, they get to make a WP test to avoid it

How about increments of 20% instead and increase it with every step. Poor quality breaks 80% of the time, common 60%, good 40% and best 20%.

I can't see how holy weapons would get any extra protection.

To open up another venue, use some weapons with the "Flexibel" trait. The rules say that those cannot be parried at all.

In adition, use "critters" to attack them. The RT rules say that natural weapons (as warp weapons) are immune to the shattering effect of the parry of a weapon with an energy field. (p. 116; "Power Field")

Ah, crap! You already postet that yourself. Sorry for useless post

Let me set up a Scene: The pc a chargeing a group of Eldar Corsairs, the Pc a sliceing down the Corsairs, with there dangerous and abit overpowerd power weapons. Suddenly after they have taking down almost all the Corsairs, a new and mystical Eldar Charge the Powerfull Rogue trader and his Trusted Body Guards, The Corsai drawn his Mono Sword and strikes right down on the Rogue trader, but the rogue trader parry the attack with his excellent Swordman Skills. The Corsairs Weapon shattered when it touch the Dangerous Power Sword. The Corsair look down on his weapon abit Disappointed. Then he draws his dangerous Xeno Created Sword. The rogue trader attack the Corsair, but the Corsair Draws his weapon infront of the attack and parry the rouge trader attack. Suddenly the power sword powerfeild shots down like all the power from the Battery gone out, and the Eldar starts to laugh down and slice right through Rogue traders unpowered Power Sword.

Engerystealer:

Damage: 1d10+4 Pen: 4 Speacial: Engery absorbing, Ballance.

Engery Absorbing: When ever a Weapon with the quality hits a Weapon the Powerfeild Quality, the user takes a Tech use test, if Succes the weapon the before had the powerfeild quality lose it, and now only counts as the mono upgraded version of this weapon. The Weapon with the Engery Absorbing Quality now also get the powefeild quality to the end of the encounter. Remember this only works if the weapon is drived by Battery or something like that.

Hope you can use it ;D

Have the Eldar shown this kind of weapon in any of the canon ?

I could use it for some of the vaguely defined xenos, or some of my own creation. But I'm not going to give this kind of thing to the major players if they don't have it.

They do have Haywire Grenades. The effects are anything from an EMP to a virus-filled data-burst that tries to shut down nearby electrical systems. The tabletop rules these days just have them affect vehicles, but they used to shut down terminators just as easily.

It's not inconceivable that haywire technology could be incorporated into a weapon, though I'd make it a baton of some kind to be dual-wielded with a real weapon.
