A few notes from my side, some of which are off topic:
To Dalvyn's post: first I think you wrote haste instead of slow once, but that isn't really important. The other thing I want to ask, does flee <direction> exist/work? I believe there has been a forum post about it somewhere, basically saying that it does not. If it does exist, probably I am soing something wrong, because flee<direction> has never worked to me.
Now back to the topic: For me it seems the haste spell is a very powerful spell, and though I agree to Dalvyn abut more power for wizards (

) I think there should be some bad effects on it:
The first thing is something I remember from playing Baldur's Gate: After the spell wears off, the character was tired and needed to rest. As theer isn't any coded tiredness here in this mud. I would think a good substitution would be to let it double the amount of stamina taken away by fighting. Something which I would also find interesting, would be that you use way more stamina for moving on the map, maybe as much as if you were running/sprinting constantly. On the other hand it could also reduce the lag while moving so that you really do run/sprint while moving around with haste. In my opinion, this would greatly reduce warriors having that spell cast on themselves(maybe even for 24 hours) then just go and kill things to train themselves up. It would be rather used to fight a single, or a small group of monsters(like for example, a dragon, and not kill dozens of ogres in certain areas in the game, and use this spell just because you are more quickly finished with it).
The next thought to thiis is a question: You said haste increases the number of attacks a character gets. Does it also increse the number of spells/reduce the lag time of a spell? From how Dalvyn explained the rules for the slow spell, this would be a good thing as well.
The third point might be obsolete with what Dalvyn explained, but as I am not sure how well D&D rules and FK rules/code agree with each other, i'll ask it anyway: What happens if a character has only one attack/round and gets slowed? Does he either is unable to attack anymore, or does he get one attack every two rounds, or will slow have no effect at al(if you go by the "all but one attacks get taken away" statement)?
Finally, something i do not know from D&D like games, but from another RPG system, but which could also be applied here: The haste spell there does increase the speed with which you can move, but it does not increase your ability to think/coordinate, meaning that while you might have one more, or double the amount of attacks, you have way worse chances to actually hit the target.
Okay, that#s all i can think of for now
