### Traits
**Shadowmeld.** While in dim light or darkness, the Shadow-Tether is invisible unless it attacks or casts a spell.
**Unseen Execution.** The Shadow-Tether has advantage on attacks against any creature that hasn’t taken a turn yet this round or is unaware of its presence.
**Warranted Lethality.** Against targets under a Vein Writ or Lawbrand, the Shadow-Tether scores a critical hit on rolls of 18–20 and ignores resistance to necrotic and psychic damage.
**Blood Echo Pulse.** The Shadow-Tether can sense the heartbeat of any living creature within 60 ft. It knows direction and distance but not identity unless it has tasted their blood.
**Mythic Resistance.** When the Shadow-Tether fails a saving throw, it can choose to succeed instead. 3/day.
---
### Actions
**Multiattack.** The Shadow-Tether makes three attacks with its Silencer Blades or two attacks and uses _Fade Between_.
**Silencer Blades.** _Melee Weapon Attack:_ +15 to hit, reach 5 ft., one target.
_Hit:_ 21 (4d6 + 8) slashing damage + 18 (4d8) psychic damage. If the target is surprised or restrained, they must make a DC 20 Wisdom saving throw or be stunned until the start of their next turn.
**Fade Between (Recharge 5–6).** The Shadow-Tether teleports up to 60 ft. to an unoccupied space it can see in dim light or darkness, then makes one weapon attack with advantage.
**Vein Garrote.** _Recharge 6._ As a bonus action, the Shadow-Tether attempts to garrote a creature within 10 ft. A DC 21 Strength or Dexterity save is required or the target is grappled, restrained, and silenced for 1 minute. A creature restrained this way can repeat the save at the end of each of its turns.
