Locaha's hand crashes into you, a wall of blackness -- it's like getting hit by a semi truck, to use a completely anachronistic analogy. Even with the shielding, it knocks you out of the sky, and if his skin makes contact with you it's like being slashed with razors, burning cold.

(And his other hand is squeezing shut around Mau and Selenia, while Mau futilely tries to drag him away.)
