Blade of Nocturne

Your time bringing down prey has taught you there are ways to do it cleanly and quietly.

Attacks you make with light or finesse weapons ignore slashing and piercing damage resistances on your first attack each turn.

When you attack and hit a humanoid with a surprise attack, it must make a Constitution saving throw (DC 8 + your Dexterity modifier + your proficiency bonus). On a failed save,  if the creature is below a certain CR (see table below) they are reduced to 0 HP and are dying. You may use your reaction to immediately make a Dexterity (Stealth) check, against the other creatures' Passive Perception, to conceal your actions from any creatures within sight.
