Here, i will provide my build if someone wants to try for themselves.
Things to always remember:
Stealth provides you with a massive evasion boost as well as gives you the ability to use backstab.
So naturally, you should be attacking from stealth, ALWAYS.
Skills to take:
*Seduction Lv1
*Seductive Assassination
^Take these two first before anything else to maximize item gains.
*Combat Training is the third perk you take.
*And for last, both: Vital Strike Lv1 and Vital Strike Lv2
Starter gear you can easily get:
*Weapon: Acid Fang, can find it on the ship.
*Accessory1: Dazzling Pareu to boost acrobatics.
*Accessory2: Training Scarf to boost Backstab.
*Accessory3: Leather Sandals for extra evasion.
=======================
I repeat again that this will require you to always start combat from stealth.
In combat use acrobatics to further boost evasion, and use backstab to destroy your targets.
Also my starter perks were: Lucky and Versatile.
You could easily replace Versatile with Combat Veteran to start at level 3 for easier gameplay.
This build also provides you with pretty much all the luck skills such as full heal and lucky strike.
There is nothing in this game that cannot be utterly owned with this build.
