Viral by Wurmatron
A mod about mobs that get infected. Viral makes them stronger and spreads along with hurting your animals.
Adds two new ores to the game. Viridium spawns in the overworld, while Ostrium spawns in the nether. Scepters are crafted by placing a(n) Ostrium/Viridium block on top of two sticks.
