What are the Canon ways to kill a Daemon (as opposed to just blasting it back into the warp which seems to be the normal method). The solution I cam up with for the finale of a campaign was to allow the Greater Daemon in question to be summoned as part of a ritual to drag a world into the warp and then unleash other rival greater deamons on it figuring that they would tear apart its soul. My players seemed to think that this method was somewhat extreme and their characters found dealing with the consequences of it somewhat disastrous. They may well want to kill a Daemon off in the eventual Ascended sequel and I would like to see what methods could be available when I am planning the game

I guess you could use other demons to kill a demon, but its very risky as any number of things could go wrong.

You could perhaps use the Holocaust fire spell depending on how you read the description.

In my opinion you may be able to kill a demon if you can prevent it from returning to the warp with Warding or a ritual maybe. Perhaps this would just kill it though as it feeds off warp energies to begin with.

It seems easier to trap a demon instead of killing it, like to an item or a person. Then you can get rid of the item without destroying it and the problem should be solved until someone finds it again which could take centuries. An by then its someones elses problem

Well, this is where a creative party might come up with some awesome stuff. Daemons in the material world need to maintain a constant stream of energy in one form or another. Usually, this is a local cult that summoned them and worships them, and their worship/sacrifices will keep it here in the material realm… Unless they're stopped. Or perhaps there's a rift somewhere that's allowing them to pull energy from the warp? That can be discovered and severed.

Basically, they can only make themselves "real" with a source of energy. Cut off that energy, and OVER TIME they will weaken. Who knows how long this takes…?

I read somewhere (i believe greyknights related lore) that using it's true name and then slaying it makes it take around a thousand years before it can re enter the warp/rejoin the other daemons thus it won't be an issue for a millenia. I'd double check that before calling it cannon and i think my friend showed me it in the Grey Knights OmniBus. Again double check hope i helped.

It's in the first book of the series; it's been a while since I read it, but I seem to recall that knowing the daemon's True Name allowed the Grey Knights to banish it…?

Thanks for the ideas. I expect my players to try and come up with their own probably including things I have never thought of, I was just trying to get an idea for the options and make sure they had at least one avialable to them other than setting daemons on each other which they know in character works but have seen its unpleasent consequences.

I expect them to try and kill the Daemon Prince in question as banishing it for a thousand years is just leaving the problem for someone else who may get suprised by the return of the daemon (also this particular daemon probably poses an intolerable threat to the sector from within the warp)

Yeah… About that… Banishing it is actually better. Killing it just weakens it and sends it back to the warp. The Grey Knights are doin it right. I am not aware of any way to permanently destroy a daemon, but I'm sure someone in here will know of one?

I think they do the whole immortal thing of they can't really die again from what i know, also it wouldn't really be just leaving it for somone else in my opinion because generally speaking that is the best you can do. Immortal as in forever, unending, so long as they are worshiped they shall return, hence well the inquisition.

I think it wouldn't be unthinkable that they would notify some organization either directly or through inquisition chanels so that they could handle it from there, or just record what went down so that appropriate cautions can be implented.

These are just some ideas i have that you could use if you like. Have fun with you campaign! And if you want ideas or quisitons i think most of us are happy to help ^.^

A misunderstanding I mean destroying or killing the Daemon not its avatar in the real world , as you say banishing would be better but thats not what I am talking about . I FULLY understand that blasting a deamon with a plasma gun in the face just disrupts it and sends it back to the warp I am looking for methods of killing the daemon

I am reasonably certain that in some older Warhammer/WH40K books it is established that Daemons can die . The only 2 methods which I remember are

1)Psyk-out weapons

2Other Daemons killing them in the warp.

(also I believe there is a Daemon which was killed by an Inquisitor in Purge the Unclean)

As they take the pattern of disruptions in the warp , I was thinking that blowing a warp engine or anything else which badly disrupts the warp may do so if the Daemon cannot avoid the effect

Those things make a lot of sense, actually. I'm not familiar with a lot of the fluff on Grey Knights, but that would be the place to look. If psyk-out or psycannons can kill Daemons, I would accept that logic. In short, though, the cell of acolytes that he's talking about will more than likely be completely and utterly unable to get weapons like that. Ever.

My understanding is always that the Inquisition is more about trying to keep the horror at bay, but there's little or no "progress" in terms of really fighting back in a lasting way. Perhaps this is why some Radicals have decided that the obvious tactics are not enough, and have looked at alternatives.
