That's not a bad starting roll, but the thing is that you can get succubuses (which evolve up to lilith) from normal farming. If you have the patience with rerolling, it really is better to get a Valk, Green Odin, or Viper Orochi as your starter, since you can ONLY get those from the rare egg machine (which means pumping money into it if you've already progressed too far to think about rerolling).So just starting out and I got a 5star Lilith the Witch of the Night on my 4th redo of the tutorial. Worth keeping and moving on?
Believe me, if you get into the game and progress through the technicals, you will start wishing that you had gotten a decent starter...before I got lucky and pulled a valk after paying $30 for rolls, I was seriously considering tanking my entire account to roll for a valk.
Just think of it this way....every time you reroll, you are saving $5. That helps ease the pain of rerolling on a gold egg.
Editted to add: I rolled well over 50 times before I got a Vritra, and if I knew then what I know now, I would have kept rerolling.
