Arcane Singularity is created by fusing Nitor and Alumentum in a Thaumic Infuser
Arcane singularity is both a fuel, and a destructor. It can be right clicked and thrown, which after travelling a bit of distance breaks blocks around it and sucks them in and destroying them. It may also kill mobs including the player
It's second use is the fuel source for the functioning of an Arcane Bore.
