[net.games.rogue] Teleportation, die rolls

nathan@mit-eddie.UUCP (Nathan Glasser) (12/19/83)

Someone mentioned before something about rings of teleportation
which weren't cursed. To the best of my knowledge, any rings of
teleportation which you do not remove the curse from are always
cursed. Can anyone say anything otherwise about this?

There was a question about the difference between things like
1d5/1d5, 2d5, and 5d2. 2d5 means 2 rolls of a 5-sided die (1-5).
5d2 means 5 rolls of a 2-sided die (1-2). There is a big difference
in what you get from these. 2d5 has an average of 6, while 5d2 has
an average of 7 1/2. The difference between 1d5/1d5 and 2d5 is that
1d5/1d5 signifies that the monster gets two attacks, and each one
that successfully hits is 1d5 for damage. So it is always better
to be attacked by a 1d5/1d5 monster than a 2d5 monster (not that
you get to make that choice.)

Well, most of the time.  However, imagine that you have 2 hit points left,
and the monster has a 20% chance to hit you.  If the monster does 2d5, he
will kill you 20% of the time.  If the monster does 1d5/1d5, he will kill
you (.16 x 3/5) + (.16 x 3/5) + .04 = 23% of the time, since he gets two
tries, and either one of those tries has a good chance of doing you in.
