Heat Lightning

This spell is a part of the Electric Shock spell chain and can be found in the Electric Shock rune stone.

Heat Lightning is a rare phenomenon often only experienced in hot evenings within warm climates. Those who study it might tell you that it is lightning seen from a very distant storm, but the navitamancer knows different - it is energy expressed without a storm but by the power of the Seraphim and its righteous might. After warning the enemies to leave their friends alone, the navitamancer finally reacts and calls upon this power. Their fingers crackles with red hot lightning as it shoots outward in a straight line in front of you. The lightning burns and passes through each and every target until it finally exits the field of battle and dissipates. The first target in the straight light catches the lightning at its most potent, receiving 4d12damage. This target scatters the energy slightly, causing it to arc to one space to the left and one space to the right, hitting any target in those spaces for 4d8 damage. Each additional target in the straight line path receive the damage slightly less than the target before, decreasing by 1 die size but never decreasing by die amount. Therefore the next target may take 4d10, the following 4d8, and do forth. The die amount does not decrease past 4d3, with any remaining targets in the line taking 4d3 damage. Furthermore any target outside of the first do not arc the lightning. The heat lightning is also indiscriminate. It will hit friend or foe.
