Swiftfoot

Choose a willing creature that you can see within range. Until the spell ends, the target's speed is quadrupled.

If any creature preforms a succesful hit on the target, the target can take a Reaction to make a Dexterity saving throw with a DC of 15. If the target fails the Dexterity saving throw they take half damage of the damage they would've taken. If the target succeeds the Dexterity saving throw they don't take any damage as they dodge the attack and gain 40 feet of movement, after they end with their movement the attacking creatures turn continues.

When the spell ends, the target can't move or take actions until after its next turn, as a wave of lethargy sweeps over it.
