Agonisers and Poisons and Strength (oh my!)

This has probably already been asked, so I apologise in advance:

We all know that Agonisers are excellent for taking down carnifexes or wraithlords, when your meagre Strength would otherwise do nothing, but what about the other way round, when you would otherwise wound on a better roll
For example, a Furiously Charging Hekatrix (S4) attacks a Hapless Guardsman(T3) with her agoniser Normally she would wound on 3+, but is it only 4+, because she uses her agoniser?

Ditto with poisoned weapons. A FCing Wrack(S4 again) will wound anything on 4+ thanks to it's poisoned weapons, but if it attacks a T3 guardsman, does it wound on 3+? Does the poison reroll still apply? I'M SO CONFUSED!
Please help, before I am driven insane.

Agoniser always wounds on a 4+, that's it.

Poisoned weapons always wound on a fixed number, but, if your STR is equal to or higher than the opponents T then you get re-roll to wound.

If the model has a normal close combat weapon aswell then you have to go with what the poison says.

I guess best answer would be:
You must stick with weapons penalities and advantages. And no on-offing special weapons if You don't have "normal" CCW* .

So Agoniser always hit on 4+, same with Poisoned Weapons.


pistol don't count as one, it just give +1 attack if paired with one hand weapon.

Agonisers work like stun guns, it's unimportant how hard you hit someone.

And of course, if you use a special weapon, you have to use it, so all bonuses and penalties apply.

And the other Wyches will pick up the slack on the Guardsmen anyway, natch.
