There were two trophies awarded from the Zombie Event. Due to an unknown delay, the trophies were given out a few days after the event to any player who had attended it previously.
Zombie Trophy Edit
Gives all zombies in the area weakness, making them deal 0 damage. They still deal knockback and most will likely still damage your armor.
While Raffhawk09 suggested the Zombie Trophy were to turn horses into zombie horses, this was never a thing.
Zombie Charm TrophyEdit
The Zombie Charm Trophy is a golden zombie head with red eyes. It was designed by MrCocaCoda. It was obtained by trading a zombie heart with a Moderator or Admin. This trophy is the second of two trophies from the Zombie Event, the other being the Zombie Trophy.
Wearing the Zombie Charm Trophy gives zombies around you jump boost. Once they walk up a block, they will fly into the air. If they take the full fall damage twice in a row, they will die.
