Max Friendship Rank on DB Legends

So guys I am new around this parts and been playing DB Legends from past 2 months and I have the following question:
I been doing “Let´s Fight!!” event only with Kefla, now currently her friendship rank is lv 12 is there any limit(in friendship rank)? I like to max before going to another character.

P.S: I know that I only need like friendship rank 2 to learn special moves to Shallot but I am just doing this for fun.

Same. Just started and trying to find more then the event to rank up friendship

the limit is Level 20, but there aren’t any benefits over Lv. 2 for shallot’s blue card. Lv. 5 may be needed for missions. There might be a few Z missions that can give you small amounts of cc.
