Emerald Armor and tools have been added in along with Redstone Infused armor being diamond, iron, gold, and emerald all of which is better than the original armor. For example Redstone Infused Gold Armor is better than normal gold armor but still worse than iron armor. Each Redstone Infused material is just the material surrounded by redstone (iron ingot surrounded by redstone for the redstone infused iron ingot). Each armor set has custom enchants for each infused armor piece equipped.
Infused Redstone now has its own Discord Server: https://discord.gg/v2qdqCfR
