Extra moves?

[Chud]

So I'm still finding new stuff every once in awhile... I picked up a randart set of boots that has +10 speed and also +1 extra moves. What is "extra moves"? From the name it sounds like you can take two actions per turn instead of one, making it somewhat comparable to an additional +10 speed in many situations - but that seems very powerful, so I'm not sure that's really what it means? Will experiment...

Also, as an aside, minor bug which I'm sure is already known - if you read a scroll that can't act on anything the message makes it seem like you didn't use it, but you did; for example, read an unknown scroll that turns out to be "remove curse" when you don't have anything cured, it says "you have a scroll of remove curse" but you don't anymore.

Extra moves is the same as speed (lowers the energy requirement per turn), but it only applies to movement. So you move as if you had +10 speed, but fight as if you had +0.

Say you and a monster are both speed 3.0, you are actually 4.0, and thus with carefully moving, you could outrun say Azog, and heal up before returning to the fight.

I thought it was a little different. I thought it was speed produces energy, and with extra moves moving costs less energy. If, surprisingly, my memory is correct, speed 2x combined with moves +1 means you are moving at 4x not 3x. It is particularly important, if true, to avoid the non-linearity of energy generation at high speeds.

Extra moves is a bit broken in that it stacks as a separate kind of speed on top of regular speed. If you have 30 speed in Angband you will be equal to Morgoth. If you add +10 speed up to 40 speed you will be *slightly* faster than Morgoth since speed stops increasing linearly above +28 speed. However if you add +1 movement speed when you have +30 speed, it's not the same as adding +10 speed in the form of movement speed. Instead, it *doubles* your movement speed, and thus is completely non-affected by the diminishing return of regular speed beyond +28 speed. So you while you are moving about the dungeon with +30 speed and +1 speed you will be moving twice as fast as Morgoth, not *slightly* faster than him.

In other words +1 momvement speed doubles your speed rather than adds to it. +2 movement speed triples your movement speed and +3 movement speed quadruples your movement speed. If you have 30 speed and +3 movement speed you will move almost 12 tiles down the dungeon hallway before the paladin chasing you moves one square. (!) And you will move 4 squares down the hallway before Morgoth will move 1 square after you.

Another interesting thing about movement speed is it reduces the number of turns you take. So if you are running down the hallway with +3 speed, you will only tally 1 turn for every 4 squares moved in the dungeon. You thus are able to get very low turncounts in a game where you find a movement speed artifact early on.
