Chelsea's Insightful Strike

As part of this spell, you must make a weapon attack against a creature you can see within 60 feet. You divine the creature's defenses and reactions, granting you insight into your attack.

Roll your attack with advantage. If you roll a 19 or 20 on the die while using this spell, the attack is a critical hit.

At Higher Levels: For every spell level above 1st you cast this spell, you land a critical hit on one less number on the die roll (18 at level 2, 17 at level 3, etc.)
