Baren Calserio

Harvester of Souls. Whenever the wizard reduces a creature to 0 hit points, if it is on the same plane of existence as its phylactery, its soul is captured and the phylactery becomes charged.

Undead Form. The wizard is both undead and humanoid, gaining the following benefits:

• Spells and abilities that state effects or conditions specifically regarding Undead of a specific CR have no effect on the wizard.
• If a spell or ability other than your own would cause the wizard to gain hit points, it gains that many temporary hit points instead.
• If the wizard is reduced to 0 hit points and falls unconscious as a result, any healing it would receive will stabilize it and leave it on 1 hit point and unconscious.
• The wizard stops aging. It is immune to effects that would age it, and it cannot die from old age. In addition, the wizard does not require air, food, drink, or sleep.

Spellcasting. The wizard is a 13th-level spellcaster. Its spellcasting ability is intelligence (spell save DC 19, +11 to hit with spell attacks). The wizard has following wizard spells prepared: 

Cantrips (at will): Infestation, Mold Earth, Toll the Dead, Minor Illusion
1st level (4 slots): Charm Person, Mage Armor, Shield, Witch Bolt

2nd level (3 slots): Darkness, Invisibility, Misty Step, Scorching Ray

3rd level (3 slots): Counterspell, Fireball, Dispel Magic, Fear, Vampiric Touch

4th level (3 slots): Blight, Polymorph

5th level (2 slots): Bigby's Hand, Dominate Person

 6th level (1 slot): True Seeing

7th level (1 slot): Delayed Blast Fireball

Observant. Quick to notice details of its environment, the wizard gains the following benefits:

• Increase your Intelligence or Wisdom score by 1, to a maximum of 20.
• If the wizard can see a creature's mouth while it is speaking a language it understands, it can interpret what it's saying by reading its lips.
• The wizard has a +5 bonus to your passive Wisdom (Perception) and passive Intelligence (Investigation) scores.

#NOTMYKINK. +1 to wisdom saving throws regarding magical effects associated with undead creatures and magical items with necromantic properties.

Tactical Wit. The wizard gains a bonus to its initiative rolls equal to its Intelligence modifier.

Power Surge. The wizard can store magical energy within itself to later empower its damaging spells. In its stored form, this energy is called a power surge.

The wizard can store a maximum number of power surges equal to its Intelligence modifier (6). Whenever the wizard finishes a long rest, its number of power surges resets to 1. Whenever the wizard successfully ends a spell with dispel magic or counterspell, it gains one power surge, as it steals magic from the spell it foiled. If the wizard ends a short rest with no power surges, it gains one power surge.

Once per turn when the wizard deals damage to a creature or object with a wizard spell, it can spend one power surge to deal extra force damage to that target. The extra damage equals half its wizard level (6).

Durable Magic. While the wizard maintains concentration on a spell, it has a +2 bonus to AC and all saving throws.

Harvester of Souls. On its turn, as an action, the wizard consume any number of charge levels from its phylactery to regain a single spell slot. When the wizard regains a spell slot this way, the spell slot's level is equal to one third of the charge it consumed, rounded down.

Rift to the Dreadscapes. As an action on its turn, the wizard can choose a point within 5 feet of itself to open the rift. Once opened, the rift stretches out from that point to a sphere that has a radius of 20 feet.

When a creature other than the wizard enters the rift's area for the first time on its turn, or starts its turn there, it must make a DC 19 Constitution saving throw. On a failed save, the creature suffers 10d10 necrotic damage, or half as much on a successful save.

Undead creatures are immune to damage from this ability. The rift remains open for 1 minute, but closes if the wizard becomes unconscious. Once the wizard uses this ability, it cannot use it again until it completes a long rest.

Opportunity Attack. The wizard makes a melee attack.

Spells. The wizard can cast the following spells as a reaction: Counterspell and Shield.

Arcane Deflection. When the wizard is hit by an attack or fails a saving throw, it can use its reaction to gain a +2 bonus to its AC against that attack or a +4 bonus to that saving throw.

When it uses this feature, the wizard can’t cast spells other than cantrips until the end of its next turn.
