In your opinion, which primary stat is the best?

A mass attack, like a rain of fire, covers a good area, so you won't lose out, and the Fontomites will disappear, almost certainly! Is Banish 100% effective? Please correct me if I'm wrong!

If you cast Phantom on Cerberuses or Vampires, they will immediately start acting, and the Phantom will do a lot of damage before your hero's turn comes.
And there is no Banish spell.
