Level 3: Agile Combatant

You gain the following benefits while wearing Light Armor or while unarmored.

• Swift Strike: When attacking with a finesse or light weapon in one hand and wielding no other weapons, you can make an attack with that weapon as a bonus action immediately after the attack.
• Melee Shaman: When casting spells that require you to make an attack or that affect a weapon (such as Ensnaring Strike, Hunter's Mark, Magic Weapon, and similar spells), you can cast the spell as a part of an attack action rather than as the usual casting time. The effects apply to the attack as normal.

Level 3: Melee Precision

A number of times per long rest equal to your Dexterity modifier + your proficiency bonus, you can give a melee attack with a finesse or light weapon one of two effects:

• Precise Damage: You count all damage dice as having rolled the highest possible number.
• Precise Aim: You gain advantage on the attack roll.

Level 7: Cunning Aim

Your attacks with melee finesse or light weapons count as magical for the purposes of overcoming resistance and immunity. In addition, you can change the damage type of your attacks with melee finesse or light weapons to be Force damage.

Level 11: Damaging Momentum

If you move at least 10 feet before making an attack with a melee light or finesse weapon, the attack is a critical hit on a natural 18, 19, or 20.

Level 15: Weak Point

You have advantage on all attack rolls made with finesse or light weapons, and you roll the damage three times and take the highest result. In addition, the target of your Hunter's Mark spell always counts as having vulnerability to damage dealt by you with melee light or finesse weapons.
