Are devils worth 7 blood each?

Hm but this would perhaps make dome wars a bit more interesting . If you bombard the domes with dozens of cheap spells like seeking arrow and at the end of the spellcastchain include a few fires i think this would be funny

Spells are cast in random order. You have no way to make your spells go in any particular order, and a proper set of domes only gives a 7% chance that any one spell will make it through.
