Master Bladesinger

You master the secret arts of the Bladesinging traditions. You gain the following benefits while activated:

• You can add half your Intelligence modifier (minimum of +1 and rounded up) to the attack rolls of your melee weapon and rest to damage while your Bladesong is active.
• When you make a running jump, the distance you cover increases by a number of feet equal to your Intelligence modifier while your Bladesong is active.
• You have advantage on Dexterity Saving throws while your Bladesong is active.
• When you roll initiative and have no uses of Bladesong remaining, you regain one use.
• When you take any action on your turn, you can cast a spell (can be another and cast time of action) of 1st-level or higher as a bonus action.
