The Pandemic is a Hardmode yoyo dropped by The Plaguebringer Goliath. Similar to the Oblivion, the Pandemic constantly fires plague seekers at nearby enemies; plague seekers deal half the damage of the yoyo. Both the yoyo and its plague seeker projectiles inflict the Plague debuff.
It can stay in the air forever and can reach up to 22 tiles.
Its best modifier is Godly.
