Ensnare Soul

You cast this spell during a creatures final moments allowing you to grip onto its souls has it leaves its body, allowing you to entrap it within a coin. 

This spell is cast as a reaction and requires a golden coin to cast which is consumed once casted. Upon doing so, you can either heal 2d6 plus your casting modifier or store the soul within a golden coin and receive one soul coin. You can store up to as many soul coins from this spell equal to your proficiency score. If you already have the maximum allowed amount of soul coins at one time, you automatically heal instead.

If this spell is cast at 4th level or above, you heal an additional d6 per additional spell level.
