Gatekeeper's Aura

Any creature that starts its turn within 10 feet of the phylaskia must make a DC 15 Wisdom saving throw. On a successful save, the creature is immune to this aura for the next 24 hours. On a failed save, the creature has disadvantage on saving throws and its speed is halved until the start of its next turn.

Undead Fortitude

If damage reduces the phylaskia to 0 hit points, it must make a Constitution saving throw with a DC equal to 5 + the damage taken, unless the damage is radiant or from a critical hit. On a success, the phylaskia drops to 1 hit point instead.

Vigilant

The phylaskia can't be surprised.

Actions

Multiattack

The phylaskia makes two longsword attacks and uses its Strength Drain once.

Longsword

Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 14 (2d8 + 5) slashing damage, or 16 (2d10 + 5) slashing damage if used with two hands, plus 11 (2d10) necrotic damage.

Strength Drain

Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 12 (2d6 + 5) necrotic damage. Unless the target is immune to necrotic damage, its Strength score is reduced by 1d4. The target dies if this reduces its Strength to 0. Otherwise, the reduction lasts until the target finishes a short or long rest.
