2. I position the monsters before the battle (on the map), placing the slower ones near the archers...
water magic isn't really needed, well unless it's to remove enchantments, clone, and sometimes teleportation works...
movement on water is rarely needed...
fire magic has good attacking spells, air magic will be useful with haste, fly and dimensional gate, and earth - with slow and town portal...
well and of course some other spells
What is offensive fire magic? Is it Inferno? Or Armageddon, which kills everyone? =)))
And Earth has a 5th-level spell, I don't remember the name, it looks like a cauldron... Disintegration (Immolation) or something like that... It's a powerful spell.
Air has Lightning and Chain Lightning...
