Elvo's True Strike

You point a finger at a target within in range. Your magic grants you and any creatures you designate a brief insight into the target's defenses. The next attack roll against the target gains a 1d4 roll added to their roll.
The die that is rolled increases to a 1d6 when you reach 5th level, a 1d8 when you reach 11th level, and a 1d10 when you reach 17th level.
