True Strike 2.0

You point a finger at a target in range. Your magic grants you a brief insight into the target's defenses. On your next turn, you gain advantage on your first attack roll against the target, provided that this spell hasn't ended.

If this spell is cast at a higher level, then for each level the caster can choose an immunity, resistance, or vulnerability to uncover about their target. If the target has none of those features then the spell slot is still used up.
