Bladesong (3/Long Rest). Provided it isn't wearing medium or heavy armor or using a shield, the bladesinger invokes an elven magic that graces it with supernatural speed, agility, and focus for up to 1 minute. It ends early if the bladesinger no longer meets the requirements, use two hands to make an attack, or ends it (no action required).

While the bladesong is active, it adds +4 to it's AC, 10 feet to it's walking speed and +4 to any Constitution saving throw it makes to maintain concentration on a spell. It also has advantage on Dexterity (Acrobatics) checks.
