SPELLS INCLUDE:
Thunderbolt: the only spell to not fly in an arc. Straightforward, very effective damage-spell that doesn't take wind into account much.
Scatterblast: A weak spell good for thinning out masses of incoming enemy units. Shoot three projectiles.
Comet: Draining all your Mana, this is the most destructive spell in the game and will devastate battlefields.
and obviously many others.
