A Keeper of Secrets Witstealer Sword says:

Chapter Approved 2019 wrote:When resolving an attack made by a model that has lost one or more wounds from an attack made by this weapon, subtract 1 from the hit roll.

If I have, say, 2 keepers, and each of them wounds with their Witstealer Swords on something big enough to survive like a Knight, then what is the result? Is it:

1) The Knight is -1, because the "this weapon" refers to (all instances of) a Witstealer Sword
2) The Knight is -2, because "this weapon" refers to this (specific instance of a) Witstealer Sword

It's that specific Witstealer Sword, otherwise it would be worded something like "... each Witstealer Sword..."

Also note that the use of the term "this weapon" is quite common in the datasheets. For example the Keeper of Secrets datasheet uses the term "this weapon" for the Living Whip and Snapping Claws in addition to the Witstealer Sword.

It all depends on what you define "this weapon" to be. GW seem to be incapable of writing rules correctly so both arguments have some validity to them.

FWIW I agree with Ghaz.

Agreed. While there is some ambiguity, the most sensible interpretation in my opinion is that it is referring to that specific instance of the weapon.

it's interesting, since a while back I asked the same question for the IG Valdor Tank Hunter which has a similar worded rule and the consensus seemed to be: RAW yes, but most likely it is not intended that way.

Theres no consensus in that thread! One person said it worked.

My position was the same as now. It's not great wording, but it makes most sense to restrict it to the specific instance of the weapon.

You are right. It would be more correct to write "it was my Impression that..." instead of "Consensus". I apologize
