Profile

In BRO there are three kinds of experiences, TRADE, COMBAT and SOCIAL. When mining, you’ll get Trade xp, when fighting you’ll get Combat xp, and when you Chat, send Neuros, or by walking through the map you’ll gain Social xp.

Each type of XP allows you to open 2 skills:  

Trade: Equipment & Crafting

Social: Personality & Psynet

Combat: Melee & Range

And when you open the two of one of these skills you will be able to open a third skill with the same type of XP:

Trade: Engineering

Social: Leadership

Combat: Tactics

In order to assign your xp you should go to Profile (1) and then select between stats or skills (Select category) depending on where you want to assign your XP.
Then you click on the type of XP you want to sort out(2) and then you upgrade the skill or stat you want to increase.(3)

In the first 7 days you can reset your experience for free --> Profile – Energy Reset XP. After these 7 days you need to pay energy or PP (50).
