Hypnotic Gaze

1st-level Vamapire Liege feature

Your vampiric master has granted you some of its charm allowing your soft words and enchanting gaze to magically enthrall another creature. As an action, choose one creature that you can see within 5 feet of you. If the target can see or hear you, it must succeed on a Wisdom saving throw against your warlock spell save DC or be charmed by you until the end of your next turn. The charmed creature’s speed drops to 0, and the creature is incapacitated and visibly dazed.

On subsequent turns, you can use your action to maintain this effect, extending its duration until the end of your next turn. However, the effect ends if you move more than 5 feet away from the creature, if the creature can neither see nor hear you, or if the creature takes damage.

Once the effect ends, or if the creature succeeds on its initial saving throw against this effect, you can’t use this feature on that creature again until you finish a long rest.

Flesh Feast

6th-level Vamapire Liege feature

The flesh of the living provides nourishment. As a bonus action, you can eat a living, Tiny beast with a challenge rating of 0 (such as a rat or spider) and regain a number of hit points equal to your warlock level plus your Charisma modifier.

Alternatively, as an action, you may make a melee spell attack against any creature to bite it. On a successful attack, you regain hit points equal to your warlock level plus your Charisma modifier, and the target takes 1 piercing damage plus necrotic damage equal to your Charisma modifier.

Once you use this feature, you must finish a short or long rest before you can use it again.

Resting Place

10th-level Vamapire Liege feature

You gain some of your master's interred earth. At the end of a long rest sleeping with it, you gain the benefits of the death ward spell being cast on you upon waking, but with a duration of 24 hours.

If you no longer possess the earth or it has been purified through the hallow or greater restoration spells, you may spend an hour entreating your master for some more.

Command the Meaner Things

14th-level Vamapire Liege feature

You may call on vermin in your master's command. As an action, you magically call 2d4 swarms of bats or rats. The called creatures arrive in 1d4 rounds and are friendly to you and your companions. Roll initiative for the summoned creatures as a group, which has its own turns. They obey any verbal commands that you issue to them (no action required by you). If you don't issue any commands to them, they defend themselves from hostile creatures, but otherwise take no actions. The beasts remain in your service for 1 hour, until you die, or until you dismiss them as a bonus action.

Once you use this feature, you must finish a short or long rest before you can use it again.
