Sulfur Part 2

Okay so basically you would add a sulfur ore type block. The drop from the block is a sulfur fragment/shard/etc (whatever sounds best). These can be crafted or smelted into a full sulfur crystal. Then the sulfur crystals can be used to craft blocks and stuff, but most importantly armor and tools. The armor, when wearing a full set, does passive damage to nearby mobs (due to the smell of sulfur), and the tools also do some poison damage with the number of ticks of effect based on their respective damage. Also, using sulfur/cinnabar to create dyes or powders could be cool. Dyes would be normal (Red dye from cinnabar powder and yellow from sulfur), but the powders on their own mixed with water and placed in a cauldron could be used to soak leather armor and apply the passive poison effects.
