This is an early version of our team builder that only has the most necessary functionalities available. We will continue to expand it till the release by adding: Relics, Light Cones, showing all stats not just Speed etc.
Be aware that refreshing the page or moving to another will reset the data - sessions storage will also be added in a future version. Also there are some issues with data not refreshing properly when you remove a character from the team in the advanced mode. Till its fixed we suggest to start playing with the advanced mode after selecting the 4 characters in your team.
