As a reaction, which you use when you make a Reflex saving throw or you are hit by an attack or missed by 4 or less that you can see, you can step back in time to avoid the effect or attack. You make the roll with advantage or attacks made against you are made with disadvantage until the start of your next turn, including the triggering attack. You can do so after the roll but before any effects of the roll occur.
You can then teleport up to 5 meters to an unoccupied space you can see that you occupied since the start of your last turn.
If the roll already has disadvantage, you cannot apply another instance of disadvantage and you must use this before the roll to cancel out any disadvantage.
You can teleport up to an additional 5 meters for each additional mana expended.
You can expend 1 additional mana to trigger this spell when a creature moves within 1 meter of you or when you take damage. If you take damage, you halve the damage against you.
You can expend 1 additional mana to trigger the spell when you or one of your allies within 2 meters of you makes a Reflex saving throw or is hit by an attack or missed by 4 or less that you can see. It can then teleport up to 5 meters to an unoccupied space you can see that it occupied since the start of its last turn.
