You can alter your perception of time, allowing you to observe events at much slower than real time. This allows you to react to any event occuring in real time with much greater precision. Of course, your body still moves at normal speed, so the benefit of this spell is metered. Once before the spell ends or is sustained, you may do one of the following:

• When you are the target of an attack, you may inflict slight upon that attack.
• When you are struck for damage, you may force your opponent to discard one damage die that they have rolled; it is treated as though it were never part of the damage roll in the first place.
• You may take favour on a saving throw made to avoid (but not to end) an effect.

When you Sustain this Spell, you reset its options until the end of your next turn. Otherwise, the spell ends at the end of your next turn.
