You create a sphere with a 30-foot radius that originates from you. A number of creatures equal to your Charisma modifier are affected by this spell while inside the sphere. Until the spell ends, the creature's speed is doubled, it gains a +2 bonus to AC, 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 this spell ends, you and other creatures affected by this spell, gain 1 level of exhaustion. If a creature leave the radius of this spell, the effect ends immediately and they cannot take an action until the start of their next turn. If you are hit and take damage, everyone under the effect of this spell makes a Constitution saving throw or take 1 level of exhaustion. The DC for this save is equal to half the damage taken by you or 10, whichever is higher.
