What is the Renew Spell? The Renew Spell is a spell which renews the body and rapidly increases the red blood cell count. In simple terms it increases the blood in the body to stop the body from losing too much blood. Unfortunately it was in widespread decline as magic casters would cast the spell on dying patients and they would still bleed out. As the Empire researched this magic it has become extremely prevalent that people just didn't understand what happened and saw the spell as a waste. It is a step within the process and is only used in that regard, however experienced magic casters will use it after using a Heal Spell to close wounds and the target will make a full recovery quickly.
