Toz's lightning bolt hadn't left a trace of its passing within the arena he and Dyra fought on.
With the element of space added to the lightning bolt, it didn't need to travel, and it appeared in front of its target almost instantly.
The element of darkness covered most of the lightning bolt's presence, but the explosive force of lightning and fire, reinforced by the weight and sharpness of metal, couldn't be perfectly concealed.
Orange, blue, and purple light burst out before the lightning bolt could strike its target, alerting everyone of its location. But even if they noticed the light, no one present would be able to react confidently to the lightning bolt.
The lightning bolt contained force and speed even Toz didn't know he was capable of conjuring. And seeing Brunswick hurt had triggered unexpectedly strong feelings of protectiveness in Toz.
