The second effect is triggered when a shocked enemy is killed. Lightning bolts strike enemies and destructable objects within Herald of Thunder's radius for its duration dealing lightning secondary damage. This AoE remains centered on the character's location if the character moves. Damage dealt by this effect cannot inflict shock, and is not an area of effect.
The on-kill effect will strike an enemy or destructible object every 250ms, but will not strike the same enemy again within 400ms.[1]
The on-kill effect from Herald of Thunder applies to enemies killed by attacks as well as spells, but not if they are killed by minions, traps/mines or totems.
