This explosive blows harmful viruses into your opponents, contaminating them and making them sick and poisoned. Any entity close enough in range to an infected entity would become infected themselves. The range for the virus is roughly 10 blocks. The infection will last forever if not treated with an antidote and will keep passing from entity to entity. This virus will slowly kill the entity, rendering them hungry and vulnerable in the mean time.
The explosive however possesses a destructive secondary effect. Should a Villager or Pig contract the virus, they will undergo a mutation into a Zombie or Zombie Pigman respectively. These mobs are immune to the effects of the contagion, though they do have a chance of becoming carriers meaning they can pass on the virus to others. In an area densely populated with villagers or pigs, this explosive can cause a major domino effect as these mobs mutate and infect other villagers with the contagion and cause a Zombie outbreak. Players are advised to have a backup containment plan, should such a thing occur...
To remove the virus fully, the player must kill all entities that are infected and must destroy and remove any items that could be infected. The virus can resurface if a infected item is in a players inventory.
