• When you hit a target with a melee weapon attack, that target takes an additional 2d6 force damage.
• Your speed is quadrupled.
• You gain the ability to move along vertical surfaces and across liquids on your turn without falling during the move.
• You gain a +4 bonus to your AC
• You gain an additional action on each of your turns. That action can be used only to take the Attack, Dash, Disengage, Hide, or Use an Object action

Immediately after the spell ends, you must succeed on a DC 17 Constitution saving throw or suffer one level of exhaustion. Regardless if you succeed or fail you cannot take an action or move on your following turn.
