Btw, if you haven't gotten all purple/blue summon yet, do NOT use any summon scrolls.
Because you cant hit them once you have them. So let's assume that a summon scroll will give you summon X(10 pull will guarantee a summon, so let's go with that)
If you pull it and don't have X, then you now have X.
If you farm X out first, you will get summon coins for the pull AND have X(because you farmed it out)
In fact, as the process of farming drops some stuff like rune, being able to farm is a perk in and of itself

Free 24 hour pull is fine, cause you cant save those, but dont use scrolls unless you've farmed everything!.
