Help with key system please

82958268

Hello!
I really like to play this game. When the Brazilian server went bankrupt I came to this.

Could someone explain a little about this system? How to combine keys? Could you do a tutorial in English?





This is my character on server 75:

I guess just a few people in here know how to do a tutorial in English. I didn't play for a long time, so, can't help bro.

Not good at English, I can only make a brief introduction about this system.
By combining different combinations, it will enhance your qualifications. The lines between the slots will be lit when you take a specified combination, and then you'll be strengthened.
For my poor English level, the combination list is too large to translate. So...maybe someone else can help you.
This is my configuration, just for reference. I'm also a magic shooter.
