Fighting Foresight

You have learned to adapt your insight and divinatory excellence to the chaos of battle. You learn the cantrip true strike, and can cast it as a bonus action a number of times equal to your proficiency bonus per long rest.

Additionally, if you are a Divination Wizard , you may gain an additional portent die at the start of combat. Only during that encounter can this portent die be used. Once the portent is used you cannot recieve another one until you finish a long rest. You may choose at the beginning of combat whether you will roll the portent, or save it for a later encounter.
