Fated Strike 2014
1st-level divination
You touch a willing creature, foretelling an accurate strike. The next attack the creature makes before the end of your next turn hits regardless of any modifiers or the target’s AC.
At higher levels
When you cast this spell using a spell slot of 3rd level or higher, the number of attacks that creature makes which automatically hit increases by one for every two slot levels above 1st.
