Oh hell- Wait! Wait, no, that had worked! The charging, nine foot tall brute suddenly shifted direction to bolt the other way around the rock.
Triumph hissed through her heart.
She had done it-! Yes, it had been magic, but rather than simply striking like a feral beast, she had used tactics and cover to aid her. I'm doing it, Cain, she thought savagely, joy flaring through her, and she turned the other way. Let him run out, past the boulder and away; she bolted the way he'd come, turning to come around behind him, to stare at his back and attempt again to unleash her magic on him.
Obieth had time to focus, now: to still her breathing as the Sentinel skidded to a halt. To concentrate on magic as he turned, this way and that, realizing that she was not, in fact, running out before him. To form her spell, to direct the air itself, to weave and to control it as he turned--his ghostlight eyes settling on her in the dark.
She unleashed it, then: to crush the air down above him, to sweep it out from beneath him, to slam him down and pin him there.
