Well, let's see now. I posted this awhile back, made some adjustments, so here goes.
Here is a melee assassin build I came up with. I think my stat distribution should be better, but here goes. Oh and the main skills are Dragon Claw and Phoenix Strike.
ITEMS:
Helm: Crown of Ages (I would socket with an UM and IST/Topaz): Delirium
Armor: Chains of Honor; Enigma; Shaftstop
Ammy: Mara’s Kaleidoscope (of course)
Rings: Bul Kathos’ Wedding Band and Raven Frost
Boots: Shadow Dancer
Gloves: Soul Drainers
Belt: Verdungo’s Hearty Cord
Weapon Combo’s
Eth Bartuc’s Cutthroat (upgraded) and Shadow Killer
Jade Talon and Shadow Killer


Skills:
20 Claw Mastery
20 Phoenix Strike
20 Dragon Claw
5 Venom
5 Shadow Master
5 Fists of Fire
5 Claws of Thunder
5 Blades of Ice
1 Psychic Hammer, 1 Cloak of Shadows, 1 Mind Blast, 1 Weapon Block, 1 Cobra Strike, 1 Dragon Tail, 1 Tiger Strike, 1 Dragon Flight, 1 Burst of Speed, 1 Fade, 1 Dragon Talon

You will have used 96 skill points for this, so it is going to be around a lvl84 when completed (if all skill quests are completed). I suggest the rest of the points go into Venom or Shadow Master.
Sort of winging it from here, but whatever.
Stats:

Strength: 180
Dexterity: 165
Vitality: 165
Energy: 80
(This is at lvl 99)

You will be using Phoenix Strike as your main skill, and with all the leach in this build, I don’t believe you will run out of mana that fast. And the Dragon Claw is your right-click attack. Remember to renew Venom and you Shadow Master once in awhile, as the venom adds 200-300 at the skill levels and the master is a good ally. I Advise an Act II Might Merc with Doom, Leviathin, Shako.
