As she watches, a pyre of Hysh starts to upwell within Ishaza, raw conviction upwelling from her core. It seethes, shines, sheds - it wants to be free, but Ishaza's discipline guides it onward, pouring from her heart out of her eyes, along its natural affinity for sight -
Then she squeezes sharply, and a bolt of hardened light leaps from her eyes to the target she's looking at, the closest one. It blows a ragged hole through the canvas bag and scatters burning straw for a good two meters.
She directs her gaze onward to the other four bags in turn, forming and controlling the pyre within her, and they too are smashed flat by concentrated light. The last bolt expends all her reserve, clearly in a calculated fashion, and she exhales and steadies herself as the internal pyre dims away. It all takes less than half a minute.
