Say what?

Jesus. A tad laboured, but looks like a legit way to pull off a peaceful massacre of Attnam. Brilliant idea Z.

Although, it wouldn't kill everyone. Petrus, if no-one else, would survive.

It's not so much that the traps were set by you, it's that they don't like you setting traps within cathedral grounds. So the answer is no, unless you have political immunity.

Another way, possibly more time consuming, but much more thorough, is to lay backpacks on every square you can. Then plant a few mines somewhere.

Another, much quicker way, is to get yourself what I like to call "political immunity". I believe there's a thread already. That should allow you to wreak all the havoc you wish without fear of retaliation.

Yeah, I was suprised when I found that out.

Requirements for necromancers to summon Xinroch.

Dwarves don't use wands. They will however pick up wands I believe. Any wands donated to the cathedral immediately goes to the dwarves' inventory.

Yeah, I think eating them or polymorphing them into something else is the only way to do it. Or luggin them around until they rot away. Not recommended
Although Slob, are you saying acid can destroy corpses? I didn't think they could be destroyed at all.

Which makes CW even more useless to the player :/

Unlikely. It's not the material, it's the fact a sword is still a weapon. Hell, I've gone on a rampage with an air scythe before and managed to wreak havoc aplenty.
