2) The matter disintegrator. Be honest, you do need to read the description of the weapon. It indicates it works better on denser targets. Thus yes, vrs someone unarmored it only does 2d6. But it adds damage based on the armor rating of the target, not the effect roll of the attack. So, some guy in Combat Armor or Battle dress is actually going to get mauled and be a pile of ashes. Give an example, AR of TL14 Combat armor is 16. That gun is going to do 2d6+16 damage to the poor guy in his TL14 combat armor. T
(2) "need to read the description" Right. Well, unfortunately, there is nothing that says you ignore the armour of the target for damage reduction. There is no special rule stated for this gun.
Therefore it must apply.
As per the description , extra damage for Effect is based on the target's armour, not the dice roll,as you rightly say, BUT damage is also deducted as per normal rules for armour damage reduction.
eg. vs armour 18
2d6 dmg + 18 (effect bonus based on armour) -18 for the armour itself
eg vs armour 6
2d6 dmg + 6(effect bonus based on armour) - 6 for the armour itself
Hence the thing will always do 2d6 damage, to a Battle Dress guy, a cat , a lamppost or a chicken.
I think if you ignore the standard damage reduction from armour, it works much better, but that is not what is written.
