When leveling up my character, I have the option to take the War Caster feat which says I can use a reaction to cast Shocking Grasp at a target moving out of melee range. However, my character does not have Shocking Grasp as a cantrip.
If I take the War Caster feat, will my character be able to use Shocking Grasp as a reaction even if they don't have it as a Cantrip?
