Many netizens are playing the game "Crystal Core COA", and many problems have arisen while playing. For example, they don't know much about the "Crystal Core" invitation code usage guide, so where is the analysis of this content? You might as well take a look at the guide content brought by the editor below, I hope it will be helpful to everyone.
1-Invitation code, can be used before character level 20
2- Friend companion code, your own invitation code can be bound to up to 4 people
3-Those who register first can invite those who register later, but not the other way around. For example, if I register at 8 o'clock, I can invite new registrations later, but those who register at 8.10 cannot invite me.
4-The registration rewards are officially stated clearly and are two-way. Both people get the same reward
A page for this event will pop up in level 5-15 games.
