Help on Magic with iDungeon

Hello
I need some help with using Magic skill on iDungeon as a primary attack style.
I got 93 Death Runes bound to my ammo, but when I go to select the "autocast" spell it won't let me selec it, because I don't have enough runes. I need help, do I have to do runes by myself each time? Which isn't very smart at all. Or what? Because if I start the dungeon without the spell, it gives me an error.

Thanks

 

Hmm, I don't think your bot can gather enough coins from the starting room to craft enough rooms. Try binding a magical blastbox or something like that. Perhaps that'll work.
