Jennifer is like any mage in an RPG. She does have magical power, but it's balanced out by very little defense. As callous as her comment is (which was probably meant in jest), she does have to let Cassie take the blows for her, otherwise Jenny dies and there's no power on the field. Glass cannons are great until they break.

 
    

When evil spreads across the land, and darkness rises and the monsters roam. When the creatures of the night make beautiful music, and the things that go bump in the night go bump with greater enthusiasm. When the world is in peril and is in need of a hero...

These guys are, sadly, the best the world can hope for. These are the adventures of the heroes of CVRPG. They mean well, they try hard, and occasionally they do the impossible...

They actually do something heroic.
