You have to be level 50 to get summons

You can get tonton for the first time you hit 50 :)

You can start capturing blue summons at 51 and purple summons at 53. For gold summons its just lucky draw from summon or buy fragments on summon shop :)

reach level 50 and youll get tonton as a summon for free, then you just click the summon icon at the bottom of your browser and follow the summon tutorial and then when you go to your main characters talents youll be able to select tonton, then when you get 10 hits in battle youll summon tonton, each summon has its own requirements to summon in battle, they are all chase skills, like on 10 hits or chases repulse and causes repulse etc.

Thanks to all replies, I'm only lvl. 37 so it's still long way to the summon talents.
