Hey!

So, I am having to deal with this issue right now- but I want to stay as impartial, by the book & official as possible: I'd rather avoid "ruling" one way or the other with my players at this time.

Were trying to interpret Weapon Jinx as written (With the Errata) and have determined a) no way in the power does it mention line of sight as a requirement. The weapon only has to be in range, the psyker doesn't even have to see it, or be sure its there. [Which, in my personal opinion, is horrible.] b) He can jam anything that's not primitive. This includes grenades, sure- but also bombs, chain, shock & power weapons. [Which aren't really supposed to jam.] By rules, these jam for one round and can then be un-jammed normally. Seeing as there are no rules to having these weapons un-jam normally, I am going to assume that means that they start working by themselves after a single round. In other words, that neural-whip that my assassin was using loses its shocking quality if the psyker takes a readied action and casts weapon jynx when the Assassin attacks with the whip.

Does this seem like a correct interpretation of the rules? I don't mind that second part- even though its very annoying, its rather logical. What bugs me is the first one- it just HAS to say somewhere that the psyker needs line of sight for his powers to work. And I can't find it.

Thanks for the help.

If you check errata you notice that first 3 sentences of weapon jinx power should be replaced with new. So you will get : “You reach into a nearby weapon with your mind to disrupt its function. Any one weapon within range that is not in the primitive weapon category instantly jams.”"The jammed weapon weapon can be cleared as normal" So there is nothing about 1 round of jamming. If weapon has jammed then it is jammed until cleared.

Second of all im not sure if you can jam power sword. I think you can jam only ranged weapon, granades, missiles. If you check weapon jams on page 196 it says that clearing a weapon takes full action and requires BS test. Nothin about WS test to unjam melee. Even if cleared weapon needs to be reloaded and any ammo in it is lost. So for me you can jam only ranged weapon not power swords, whisp, and similar.

If your psyker cannot see the weapon and trying to jam it I would rule to do psyniscience test first by him to detect a weapon through warp. Then he can use power on it if successful.

Your right in that it says that any weapon Jams, and stays jammed until you clear it- that makes sense, and that's how we play it, for Ranged weapons. But, as you pointed out, it doesn't say any RANGED weapon jams- it says ANY weapon that's NON-PRIMITIVE jams, which implies that you can use this power to "Jam" or "Disable" anything with a mechanism [Which include Shock, Power & Chain melee weapons.] Seeing as the jamming rules make no mention on how to clear a jam for these types of weapon, I figured the mechanism would short-circuit for a round then start operating normally [unjamming a melee weapon as normal doesn't involve any specific action or roll, so it stands to reason that it would work by itself after the "warp event" has passed."

As for psyniscience, I don't think weapons HAVE a warp signature- do they? Maybe if a weapon has left enough of an imprint or been used enough to butcher people, then sure... But its still an "I Rule that..." Thing, which is what I wanted to avoid hehe

Sorry if I sounded like an ass there hehe, I am still interested in hearing you're opinions about it- I am surprised no body else's players tried to weapon jynx to Jam a chain sword or something.

Edit- I know people have asked the makers of Dark Heresy questions before to get an "Official Answer" on a few things but I can't seem to find a "Contact" button, could anyone point the way?

Thanks!

Scroll all the way to the bottom of the page, look for "Rules Questions" in light grey.

Melee weapons can't jam.

Jamming is an effect that only happens to ranged weapons, therefore Weapon Jinx can only affect ranged weapons.

My groups always required the psyker to be aware of the target weapon, we didn't require line of sight.

If they didn't change description of this power in errata I would agree that you can jinx any mechanism. But they changed first 3 sentences, so no mechanism only weapon. And from all weapons only ranged weapon can jamm, because it's not mechanism that failure but the bullet getting stuck.

"But, as you pointed out, it doesn't say any RANGED weapon jams- it says ANY weapon that's NON-PRIMITIVE jams, which implies that you can use this power to "Jam" or "Disable" anything with a mechanism [Which include Shock, Power & Chain melee weapons.] "

If this would be true, then why only weapons? You could jinx anything with mechanism like car, watch. They wrote any weapon, but for me it means any weapon that is capable of jamming.

Doesn't the power itself actually wonk up all the electronics around(like stuff mentioned before?), the weapon jam being a bonus if you succeed on a WP check?

also: if you jam a grenade launcher, missile launcher or a grenade itself... can you blow it up onto the enemy? :3

No electronics, only mechanism.

Yeah it seems it has been errataed away.
