Specialist weapons

now im confused.

the BRB states that if you have 2 different CC weapons you must choose which one you use in CC and may not combine the special effects of 2 weapons.

contradictory to this is the Grey Knight FAQ which states that a Dreadknight armed with a nemesis force sword (and so a doom fist and force sword combo) gets an extra attack (as he should ref: 2x specialist weapons) but also is S10 from the doomfist and still gets to reroll hits, wounds and armour pen, from the sword.

I dont get it??

Isn't there something to do with the categorisation of the weapon.

Like with the force halberds

not when your combining the abilities of 2 weapons. i cant find any ruling other than the faq that allows for this so not sure why they have said it can be done
