Synthium

This mod adds the Synthium Ore that can be found from -64 to 11.
Upon mining this ore, you can then smelt it in which it smelts into Synthium Ingot, then you can use that to make powerful tools and armour.
Synth mob has also been added that is a very powerful mob which Synthium Armour and Swords equipped with 50 hearts. Upon defeating the mob it will simply drop a Synthium Ingot.
You will know when this mob is aware as a boss bar will appear at the top of your screen, although if you want to find it or avoid it, it only spawns in deserts.
