Gish

You have learned to mix your innate magical abilities and your rigorous martial training, to deadly affect. You gain the following benefits:  

• You learn one Wizard cantrip of your choice. Intelligence is your spellcasting ability for this spell
• When you miss with an attack with a melee weapon on your turn, you can use your reaction to reroll the attack. Once you use this ability, you must take a short or long rest before you do so again.
