Tesla Coil

The Tesla Coil is a item in Risk of Rain that deals electric damage to nearby enemies. Stops stacking after 3 times and does 220% damage when maxed.

Tactics
In order for the Tesla Coil to activate and do passive damage, the player must be in close range of the enemies. Tesla coil will generally help characters which are close ranged like the Miner, the Mercenary and Acrid. Although all characters will benefit from the item.

Jumping around while attacking will help dodge enemy attacks while the Tesla coil works its magic.

Trivia

 * The Tesla Coil's description could be a loose reference to the donation fund raised to build a Tesla museum on the former's old laboratory, by the internet artist "The Oatmeal"

Bugs
Damages Happiest Mask's ghosts, being the only negative effect for this item. This seems to be a glitch and not intended by the developers.
