Started playing at the end of September 2018. Drew my first five-star (Onatel) at the end of January 2019, but she didn’t end up being the one I maxed. Drew Poseidon at the end of March 2019, brought him to final ascension at the end of May 2019, and finished maxing him in mid-June 2019. Wasn’t sure exactly which of these you were asking about. Really, the key is, it took me about 8 months from the time I started playing to the time I had enough ascension materials to fully ascend Poseidon. If it had been a blue hero, probably sooner (pulled two scopes on mystic visions); if it had been a green, maybe a touch longer (only up to 7 tonics since I started playing, and that counts Shrikewood last week).
