Adren-O Shot

You regain 4d4 + 4 hit temp points when you inject this. The liquid shimmers a vibrant blue when the primer is activated and you gain effects listed below. You may use 1+ con mod per long rest with only minor effects. 

Until the spell ends, the target’s speed is doubled, it has advantage on Dexterity saving throws, and it gains an additional action on each of its turns. That action can be used only to take the Attack (one weapon attack only), Dash, Disengage, Hide, or Use an Object action.
When the combat ends, the target suffers 1 point of exhaustion
