The Microwave

The Microwave is a Hardmode yoyo dropped by Astrum Deus. While the yoyo is in the air, a small aura surrounds it which continuously damages nearby enemies, dealing 35% of the yoyo's base damage and inflicting the Astral Infection debuff.

Trivia

 * The Microwave emits a notable humming noise as it travels, and a beep sound when retracted to the player, mimicking that of a real-life microwave oven. Its tooltip makes reference to this, mentioning cooking.
 * The Microwave could also be a reference to the cosmic microwave background radiation in space, supported by the weapon's related boss being themed around space.
