Whenever a creature within range hits you with an attack, you can use your reaction to cast this spell. Once cast, you teleport 10 feet in a straight line away from the attacker and take half damage from the attack. After you teleport, the attacker must make a wisdom saving throw or be slowed as time begin to freeze around it. The creature's speed drops to 5, it gain a -4 penalty to AC, it immediately fails dexterity saving throws, it can only make one melee or ranged attack on each of its turns, it is unable to take reactions, and it can only take an action or a bonus action, but not both. Furthermore whenever the affected creature casts a spell with a casting time of one action, roll a d20. On a roll of 11 or higher the spell doesn't take effect until the creature's nect turn where it must use its action to cast it, if it can't, the spell is wasted.
An affected creature can repeat the save on the end of each of its turns, ending the effect on a success.
