Tiral simply nodded at the division of teams before walking back to the Captain's side. A two-pronged assault was simple enough to execute, at least, and he had already planned on interfering with the orcs' ability to move the moment he had seen their positions. Casting such magic over the entire battlefield, even if it was on the enemy's domain, though, was a bit of a worrisome job to him. He had initially planned to act a bit more conservatively, deliberately interfering with any enemies that charged at them from crucial locations, but in the end this probably worked out just as well. The only problem, of course, was if the enemy would adapt in turn and, if so, how quickly they would. "If it's a flanking attack, then something quick and simple should work fine to notify the other party. Silent, visible but not to the point of being obvious..." he pondered for a moment before sighing. "I can use my ice to reflect some light towards the other side of the forest once we arrive. That should suffice as a signal from our end." He would leave with the Captain once everything was set and done, but any more than this really wasn't necessary on his part in terms of preparations.
