Although I agree with most of the other posters, since you asked for a build, I'll walk you through the creation of one to the best of my abilities.
Since your still leveling and are new, I will assume you don't have access to any elite skills or tomes, and are still on the starter island. Also, as I don't know your secondary, I'll just use all dervish skills.
First off, start with a rez. Most players can get away without using one, as they usually have rez scrolls or heroes to cover for them, but as you're new, I would recommend one. Res Sig or Sunspear rebirth sig should be fine.
Next, an IAS. An IAS is extremely useful on any melee character, espicially warriors and dervishes because it allows for the faster buildup of adrenaline. A 33% increase in attack speed actually results in a 50% increase in damage. Heart of Fury is probably the best IAS available for you.
Now you need some attack skills. Chilling Victory, Erimites attack, and Twin Moon Sweep are all decent attack skills available to you early.
Finally, I would recommend some enchantments to fuel your attack skills. The first I bring would be Zelous renewal. A cheap enchantment that scales with Mysticism and is excellent energy management. The other two are kind of harder to decide, but I would probably go with Heart of holy flame, as IIRC, there are many undead enemies on the starter island, and Aura of Thorns, to be used as cheap fuel for your attack skills.
As for attributes, I would first pump all your points into sythe master, and then mysticism. You can place any remaining points into Earth Prayers, but its not that important, as you are bringing Aura of Thorns because it is cheap fuel, not because of the conditions.
Your final build will be
[Heart of Fury][Chilling Victory][Twin Moon Sweep][Eremite's Attack][Zealous Renewal][Heart of Holy Flame][Aura of Thorns][Sunspear Rebirth Signet]
Hardly the best build out there, but it will more than serve your purposes on the starter island.
