I'm in shock!!! I'm playing Zephyr's last mission. I maxed out the "Banish" skill, and with a spellpower of 31, it doesn't dispel a bunch of Biara's summoned mobs! oO
I had to use the Tome of Darkness and retrain the skills to darkness, blindness, enslavement, and Summon: Wall of Swords, Phoenix, Elementals, Crystals, Swarm, to complete the mission.
So, here's my question - why doesn't "Banish" work the same way it did in the last mission of Heroes 5 when I was fighting Kha-Belekh, and I could recall 30 archdevils with it?

A word in defense of the "Crystal" spell. If you create one near enemy archers, the effect will be as if your warriors stood next to those archers. They won't be able to shoot!
