Flyby. The chronodrone doesn't provoke opportunity attacks when it flies out of an enemy's reach.
Time’s Arrow. The chronodrone disorients one creature it can see within 20 feet of it. The target must make a Wisdom saving throw (using your spellcasting modifier) or be frightened until the end of its next turn. Phase Shift (3/Day). The temporal mechanisms within the chronodrone allow it to cast mirror image using your spellcasting ability.
Alter Time. The chronodrone briefly alters one attack roll or ability check made by a non-hostile creature of your choice it can see that is within 10 feet of it. The creature re-rolls the die and must use the new roll.
