Monarch's Call

You have claimed dominion over the souls of the dead, binding them to your will and forging a shadow legion under your command.

Binding the Soul. As an action or bonus action, you may attempt to bind the soul of a creature that died within the last 5 minutes and is within 30 feet. The creature must not be undead or already soul-bound. Make an Intelligence (Arcana) check against a DC equal to 10 + the creature's Challenge Rating (CR). On a success, the soul is bound and stored in your Grave Roster. On a failure, the soul escapes and you take 1d6 psychic damage. You cannot attempt to bind that soul again.

Your Grave Roster can store a number of bound souls equal to half your wizard level (rounded down). This becomes unlimited at 14th level.

Shade Points. You have Shade Points equal to your proficiency bonus. You regain all expended Shade Points when you finish a long rest.

Summon Shade. As an action, you may spend 1 Shade Point to summon a creature from your Grave Roster into an unoccupied space within 10 feet of you. The shade takes its turn immediately after yours. The shade lasts for 1 hour, or until it is slain, dismissed (no action required), or you fall unconscious. At 14th level, summoned shades no longer expire and persist until dismissed or slain.

Overcharge. If you summon a shade with no remaining Shade Points, you must take 1d12 + the creature's CR in necrotic damage per creature summoned per turn.

The King’s Threshold.  You may have a number of shades active at once based on your Wizard level

Burden of Sovereignty. If you exceed your summon limit, you must make a Constitution saving throw at the end of each of your turns or gain 1 level of exhaustion. The DC is equal to 13 + the number of shades over your limit. You may dismiss a shade as a reaction at any time.

Bloodborne Sovereignty. While below half of your maximum hit points, you may summon one additional shade without triggering the Burden of Sovereignty. This benefit ends if your hit points rise above half.

The Pale Crown (14th level). You gain the following benefits:

Your Grave Roster becomes unlimited. Summoned shades no longer expire unless slain or dismissed.

Your shades can merge into darkness or dim light as small as 1 inch wide. They may use the Hide action to become invisible while in such spaces, including a target's shadow. A creature must succeed on a DC 18 Perception check or use magic such as see invisibility to detect them (this includes like truesight and other forms.)

Empty the Crypts (18th level). Once per long rest, you may unleash your full necrotic dominion for 1 hour. During this time, you may double your active shade limit and spend Shade Points to summon fodder shades—8 Skeletons or Wights per Shade Point (your choice). Overcharging this feature costs 1d12 + CR necrotic damage per extra creature summoned.

At the end of the hour, all shades vanish. You take 1d6 necrotic damage per active shade and must succeed on a DC 18 Constitution saving throw or gain 1 level of exhaustion.
