Alarielle's Anticipate Weakness

With a quick glance into the future, you pinpoint where a gap is about to open in your foe’s defense, and then you strike. After casting anticipate weakness, you have advantage on your next weapon attack and you deal an extra 1d4 of the weapon's type. If the target of this attack would normally be immune to the damage they are instead resistant and if they would normally be resistant they instead treat the damage as if they where not resistant. The damage can not be reduced by other means.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d4 for each slot level above 1st.
