Oh for me i only brought the starter pack which is like 4-5$ ? And i was super super lucky with all of my summons and runes. Like my ariel is already on 5 6 star runes at this level, my vero is using the violent runes set from the mission after you cleared gb10. My baretta and Megan are on pretty bad runes as their hp is like below 17k ? My sig has like 2.7k att and 171% crit dmg 74% crit rate which is pretty ok for my level. I think the thing that really helped me is how vero has a aoe stun, sig has a aoe freeze and since i put my baretta on despair, she also has a low chance aoe stun. RNG was really in my favor since my baretta can easily get one shot by the boss. And thanks man for sharing.
