Plaguenade

Plaguenades are craftable Hardmode bombs. They are explosive projectiles that release 20 plague-infected bees upon explosion. Both the explosion and the bees inflict the Plague debuff on contact. The bees spawned by the Plaguenade fly much faster than normal bees and are unaffected by liquids.

Performing a stealth strike with Plaguenades causes the resulting grenade to emit a larger explosion with 3.75x the explosion radius which releases 8 more bees.

Trivia

 * The name of this weapon is a portmanteau of "Plague" and "Grenade".
