I've been looking for a Durga friend ever since I pulled her on the first day of the last godfest. I haven't even evo'd mine yet, since I can't find anyone to use her with. I've been keeping her as my #2 lead, just hoping someone would eventually shoot me an invite so I could evo her, awaken her, and start using her.
Shoot me a friend invite for a Durga up 100% of the time: 347,606,314
Assuming you use your Durga a decent amount, I'll get mine evolved and awakened ASAP
Edit: Wait, what friend slot do non friends see when they see you as a partner option for the first time? I've been keeping my Durga in Team 2, since the majority of the time I'm running B. Sonia actively (so she is my Team 1). If potential new friends only see your Team 1 lead, maybe that's why I still don't have any Durga friends...
