Cinnabar

Cinnabar is a scarlet-maroon ore that if mined, inflicts Fatal Poison for 9 seconds due to cinnabar's poisonous nature and drops 1 of its gem and 1 Mercury Droplet. 
This table compares it with the strength of other ores. It is easier to mine than Emerald, but harder than Steel, and has better loot than Steel, but worse than Emerald. All armor that has a strength better than 17 permanently inflicts Slowness unless the armor is taken off. Thorium armor grants immunity to poison, Lithite grants immunity to fire, Arsenic grants immunity to poison, Flourite inflicts Resistance 1 and Speed 2.
Cinnabar grants immunity to all poisons and fire, including wither. Rhenium Dioxide grants immunity to all debuffs.
26 and higher hardness grants Strength 1, Resistance 1, Speed 1, Regen 1, and Jump Boost 1.
