With these low stats and overall low Cosmic Evo Runes I am not going to evolve them anytime soon.
Hope it helps!
PS. Stats: Autofarming on Lv. X only - 7 Mega refils in three days (+ whatever SoT I got from game) gave me 2260 Lamia frags (incl. 10 for free from the store) and 1100 Lilith Frags. Plus around 32 LoL Frontier keys (saving for next LoL event)
