It blinks away...

But how would you know that, if you can't see it?

(In this case a ghost of some sort, before I had see invisible...)

Inquiring minds want to know!

[Derakon]

Teleportation makes a characteristic "bamf" sound effect, of course.

[Tregonsee]

You saw it, it is no longer in visible view, but it wooshes away?

And apparently long-range teleportation makes a different sound than short range, because you can distinguish the two.

In all seriousness. I'm going to see how difficult it would be to only report the message if the monster is in LoS and visible. We could add that to the "making the game harder" effort (although it really has minimal effect on that)

[Derakon]

It's occasionally useful to tell you if that quylthulg you detected awhile back is still where you thought it was.

Thinking about it, I don't really like the idea of silent teleports. Particularly for dealing with invisible monsters, it seems unnecessarily cruel to not let the player know that they've gone away (with the net result that the player will continue flailing blindly for longer).

While teleportation is a 'bamf', phase door is more of a 'pop'

After slogging through every single monster spell, I'm inclined towards the opposite view: I don't see why everything in the game should be audible to a blinded @. There seems at some point to have been a concerted effort to provide messages for blind @s in every possible circumstance, which means that @ (who is normally-sighted, and therefore doesn't have especially sensitive hearing) can distinguish between dozens of wooshes, bamfs and pops. S/he can even tell the difference between "many creepy things" and "many powerful things" appearing nearby!

Now I am being a little bit contrary: I don't particularly mind if teleport is one effect that makes a sound. I just think most of them ought not to. If a monster action directly affects the player (damage, confusion, stunning etc.) then a blinded @ would know that anyway. If it doesn't (summoning, haste self, heal self etc.) I don't think a blinded @ should necessarily be told.

OTOH pBlind is already pretty important, and to change what's audible may elevate it even more. It also would make ESP even more of a no-brainer than it already is.

Ho hum.

Any @ who gets either of these messages is on borrowed time - they're like the Angband equivalent of "ner ner ne ner ner".
