No it's nothing as cool as say a damage calculator or some of the stuff that theorycraft makes.
This is simply a pre-factions build that runs as closely to an assassin as possible.
To run this build you will need a E/W with the following attributes and skills:
Energy Storage: 4 (3+1)
Water Magic: 14 (12+2)
Hundred Blades [Elite] (Swordsmanship)
Sever Artery (Swordsmanship)
Flurry (Warrior other)
Final Thrust (Swordsmanship)
Frozen Burst (Water Magic)
Armor of Mist (Water Magic)
Conjure Frost (Water Magic)
Resurrection Signet ()
You run in fast, slow the enemy, inflict good damage, and have finishing moves.
Obviously take a cold sword on enchant and a +hp / energy off hand on enchant.
I recommend you hit your buffs. . .scream somethign stupid to pull attention and run in and do your opening combo which is going to be hundred blades / frozen burst. Flurry and hundred blaze will charge your adrenline amazingly quick.
Only thing the build lacks that all assassins should have is a self heal.
It's a fun build, and you can hit and run just like a real assassin.
I recommend you be a total whore to warriors
