Anti summoning tunnel

[K.I.L.E.R]

I am the first to say WTF?

So you dig a real deep tunnel, a monster which can summon follows you into it, when it summons you can only get attacked from the front?

An anti-summoning corridor is not straight. It's dug in a zig-zag, at least 3 deep, so that any non-ethereal, non-wall-chewing monster cannot see you (and therefore will not summon) until it is standing next to you. Once it's next to you, it has no room to summon.

Sorry if you already knew about that and this was just pedantic, I couldn't quite understand what the question was in your post.

Thanks, I did not know that.

of course remember that if monsters can pass or worse - can bore through wall the antisummoning corridor didn't help you to much.

There are wall chewing monsters?
Sorry I just read your post 3 times over until I understood the first paragraph.

A few months of play and I am still only a newbie.

You never even saw an umber hulk? (evil looking "X")

Umber Hulk was among the first to kill my chars when I discovered Angband (once upon a time ...).
Not only coming out of knowhere and confusing you he may also bring some company along ...

Oh - the anti summoning tunnel is often useful speaking of uniques summon monsters which summon summoners ...
