Muddman said:First off, the biggest problem with the build above is that you can't dance while under the effects of a rage or frenzy (I just read that, sorry).
The Rage is just a fallback for those times when you can't dance (because you are in confined spaces, grappled, etc.).
The real reason you want at least one barbarian level is for the +10 speed increase that stacks with the dervish speed increases. Mobility is the dervishes greates strength, and losing it is their greatest weakness. If you can't complete your movement for some reason (tripped, grappled, paralyzed, etc) your dance immediately ends and you become fatigued, and you can only use one dance per combat. My character usually gets mad when he can't dance.
Now I'm currently playing a dervish and some of this debate has confused me. The way we have played it, it seems that a dervish can start a dance, run in and start slashing away then (so long as he still has movement of course) move away.
Is this format correct?
Not the way you describe it. When in the dance, you have to move at least 5 feet between each attack. So a dervice with 3 attacks can start a dance, move in, attack, move 5 feet, attack again, move 5 feet, attack a 3rd time, and then use any remaining movement as he see's fit.
And don't forget that tumbling cuts your movement in half unless you take a -10 on the tumble check.
