Mother Cyst

You gain the ability to cast Necrotic Cyst spells by growing a cyst of your own. This unholy thing taints your body and soul, which means healing magic is not as effective. After allowing the Mother Cyst to grow, you become resistant to all healing magics. You also become highly attuned to Necrotic energy, absorbing it as health rather than taking damage from it. 

After the Mother Cyst has been implanted, you gain access to the following spells: 

Necrotic Awareness, Necrotic Bloat, Necrotic Burst, Necrotic Cyst, Necrotic Domination, Necrotic Empowerment, Necrotic Eruption, Necrotic Scrying, Necrotic Termination, & Necrotic Tumor (see spells of the same names)

 These spells are always prepared and do not count against the number of spells you have prepared for the day. These spells do not count against any limits on the amount of spells known.
