Assassin's Chain (17th level)

While wearing this armor, your steps make no sound, regardless of the surface you are moving across. You also have proficiency in the Stealth skill.

Power of the Assassin: As you gain more skill and knowledge from your experiences, the Assassin's Chain seems to grow and improve with you.

(5th Level) You have advantage on Dexterity (Stealth) checks that rely on moving silently. During your first turn, you have advantage on attack rolls against any creature that hasn't taken a turn. Any hit you score against a surprised creature is a critical hit.

(9th Level) You gain a +1 bonus to AC. In addition you can cast the Silence spell from the armor. Once used, the armor can't be used in this way again until the next dawn.

(13th Level) You now gain a +2 bonus to AC, instead of +1. In addition, you can cast the Invisibility spell from the armor. Once used, the armor can't be used in this way again until the next dawn.

(17th Level) You now gain a +3 bonus to AC, instead of +2. In addition, when you successfully hit a creature that is surprised, it must make a Constitution saving throw (DC 8 +your Dexterity modifier + your proficiency bonus). On a failed save, double the damage of your attack against the creature.

Made of interlocking metal rings, a chain shirt is worn between layers of clothing or leather. This armor offers modest protection to the wearer's upper body and allows the sound of the rings rubbing against one another to be muffled by outer layers.

Notes: Proficiency: Stealth, Advantage: Stealth, Bonus: Armor Class, Combat, Warding
