Battery

"'A unique battery found in the Bandit King's stash. Sends jolts of electricity through towers in range, which speed up ability cooldowns and bounce onto nearby enemies for more damage! Electricity can also supercharge abilities too!'"- Store/Inventory Description

Overview
The Battery is a Rare support/offensive hybrid tower. It sends shocks through towers in range at a constant rate, which can then chain to enemies near the affected towers. The electricity can break up into other types at later levels when it hits enemies, and at max level it can supercharge abilities that aren't on a cooldown. The table below shows the effects of Supercharge on certain abilities.
