Since the incident with the mace almost turning her face to paste, Snow had moved a lot more carefully on the battlefield. It took her time to adjust her fighting style to be quicker and less methodical. Focusing all of her energy into killing a single target worked well for stealth and assassinations, but in a large-scale battle, some of that attention needed to be shared with special awareness.
Desmond sighed with relief when he noticed she had evolved her methods quickly. Though he was not fully settled and still kept a spare eye on her in the event of her needing another assist. The Earth Mages continued to exhaust themselves and the dam grew every closer to completion. By this point, the enemy had given up in trying to attack them and simply waited for the construction to finish.
