Ambiguous' Improved True Strike

You point a finger at a target in range. Your magic grants you a brief insight into the target's defenses. Until the end of your next turn you gain advantage on your first attack roll against the target, or the target has disadvantage on any saving throws caused by the first of your actions that makes them do a saving throw.

The spell’s range increases as you level up. 120 feet at 5th level, 300 feet at 11th level and 600 feet at 17th level
