That's exactly it! Its usefulness in battle depends on how the enemy stacks are positioned and how many there are. "One wrong move" :) - and you'll "fry" your own troops. :( Not to mention that on the second turn, when you engage in melee, you won't be able to use the lightning spell anymore. :( One, but very powerful strike - it depends on the strength of the magic and the total health of the enemy. Therefore, lightning is more often useful against a not very large group of neutrals or when storming a castle without a hero defender.
