The vile Nurse

You summon the help of the Vile Nurse. She is the nurse of the ancient one's and plays to the side of her patient. 

Spell: Summon the vile Nurse Roll a 2D4+4 to gain temporary health.

If a creature attacks you with temporary health added, the creature will take half the damage done to you. This effect is active as long as the temporary health is in place.

After all your Temp health is gone the creature will no longer take damage from it's attacks on you (If a creature does more damage than your temp health, it will still take half damage done to you but it will deplete all your temp points.)

Spell:  Request Special Care from the nurse. Once per short rest you can call for aid healing 4D4+8.
