Lightning Behavior

Lightning Behavior is an attack behavior characterized by instantaneous seeking. It is part of the damage types family.

Lightning Behavior is represented on the Bloons Wiki as, the upgrade artwork for Heart of Thunder in Bloons TD 6, displaying the lightning attack that can be produced. Lightning Behavior is the strongest form of seeking; the seeking is instantaneous rather than projectile-based like Aggressive Seeking.

Heart of Thunder (Druid) and Lightning Bolt (Monkey Apprentice) are characteristic examples of this. Same applies for Ball Lightning's lightnings.
