Firstly, I talk about the plus points before 1 transfer ( include all occupations). In the 1-10 levels, the system will help you to add attribute points to your strength automatically. It is helpful to kill monsters.

In 11-16 levels, you must do by yourself, and I still recommend you to add power. Because at the beginning there are only one power +3 BUFF and a attack skill. It is useless to add others. After 1 transfer, the system will help you to reallocate attribute points. The points are manual after 16 levels.

Next I will talk about the add points on Assassin:

Strength: attack one point by one point.

Agility: strengthen attack, evade, the attack speed and cruel attack skill

Spirit: evade, hitting, common and cruel attack, cruel attack skill

Manual: add 1 point to 14 points MAXHP

Then next, I will talk about my add points program:

The occupation attribute of 16 levels Assassin: 4 strength 13 agility 4 physical

The assassin pay attention on high-explosive, but there is no stable output, it can not train level. So the agility is the most important attribute.

So my add points program as follows:

Full agility

Do not add spirit until my agility and spirit is full when my level number is 5 and 0. And after 16 levels, add 1 power per 8 levels.
