Lightning Rod (also known as Spire in the SNES/PS version) is a Double Tech used by Crono and Frog in Chrono Trigger. It's learned once both characters learn Lightning II and Aerial Strike respectively. Deals Light damage to a single enemy.
In Chrono Cross, Guile performs a similar tech called LightninRod, using a Light-based Element and his primary weapon, the Rod.
Description[]
Crono invokes a powerful lightning storm while Frog prepares his sword. Frog then jams his blade into the enemy with the pommel and hilt sticking straight up. Following this, a tremendous lightning bolt strikes the sword, electrocuting the target for a strong amount of Light damage.
Etymology[]
The lightning rod was invented by Benjamin Franklin during the 1700's. The basis behind it is that metal attracts the lightning to strike it, and then sends the current into the ground where it essentially becomes useless. However any metallic object is a good conductor of electricity and therefore Frog's sword(s) are legitimate conductors, and since Crono can control lightning its quite possible that he can direct it so that it ignores his own sword, or any other tall objects (trees, buildings, etc.)
