Relentless Slasher

Traits

Legendary Resistance (1/Day)

If the slasher fails a saving throw, it can choose to succeed instead.

Shrouded Presence

The slasher is immune to any effect that would sense its emotions or read its thoughts, and it can't be detected by abilities that sense Fiends.

Actions

Multiattack

The slasher makes two Slasher's Knife attacks.

Slasher's Knife

Melee Weapon Ranged Weapon Attack: +7 to hit, reach 5 ft. or range 30/60 ft., one target. Hit: 6 (1d4 + 4) slashing damage plus 21 (6d6) necrotic damage. If the target is a creature, it suffers a lingering wound that causes it to take 7 (2d6) necrotic damage at the start of each of its turns. Each time the slasher hits the wounded target with this attack, the damage dealt by the wound increases by 3 (1d6). The wound ends if the target regains hit points or if a creature uses an action to stanch the wound, which requires a successful DC 15 Wisdom (Medicine) check.

Legendary action uses: 3. The creature can use one option at the end of another creature’s turn and regains spent uses at the start of its turn.

Legendary actions

Slice

Vanishing Strike (Costs 3 Actions)
