Electrillium

Electrilliums are instant-use, electric-charging plants that electrify another plant.

Overview
When planted on the same tile as another plant, Electrillium will electrify it, which also charges it. In addition, she causes electric damage all around her as well.

On non-metallic plants, charging will only create the electric pulse. If the plant is projectile-shooting, however, then electrifying it turns its projectiles electric, similar to Electric Peashooter's projectiles.

Metallic plants charged by Electrillium will get their normal benefits from charging.

Plants that are currently undergoing a cooldown will have their attack restored by Electrillium. This also decreases their attack cooldown time by 25% permanently.

Electrillium is based off of the Trillium erectum flower. Its name is a portmanteau of "electric" and "trillium."

Strategies
Unlike other electric plants or Galvine, Electrillium can charge up any plant. This means that you have many viable options for charging that are not exclusive to metallic plants. Tall-nuts and Endurians can resist zombies with their high health, allowing them to get off many attacks over the course of their lifespan, and Endurians couple that pulse with their inherent attacking power.

Spikerocks and Spikeweeds can also deal electric damage while also staying out of harm's way. Players can also use Electrillium on strong projectile-shooting plants, such as Winter Melon, Citron, or Primal Peashooter, to deal even more powerful and extensive damage.

However, simply using it on metallic plants is not a bad idea. Many metallic plants are very strong and aggressive with their charge, so charging them up is very well recommended.

Trivia

 * Electrillium's almanac entry references Patrick Henry's famous phrase during the American Revolution: "Give me liberty or give me death."
