> ___
>
> ***Special Equipment.*** Rezmir has the Black Dragon Mask, Hazirawn, and *bracers of defense*.
>
> ***Dark Devotion.*** Rezmir has advantage on saving throws against being charmed or frightened.
>
> ***Amphibious.*** Rezmir can breathe air and water.
>
>  ***Draconic Majesty.*** While wearing no armor and wearing the Black Dragon Mask, Rezmir adds her Charisma bonus to her AC (included).
>
> ***Caustic Demise.*** When Rezmir dies, her body melts into acid. Contact with her remains deals 5 (1d10) acid damage; immersion in her remains deals 99 (18d10).
>
> ***Legendary Resistance (1/Day).*** If Rezmir fails a saving throw while wearing the Black Dragon Mask, she can choose to succeed instead.
>
> ***Jack of All Trades.*** Rezmir can add half her proficiency bonus, rounded down, to any ability check she makes that doesn't already include her proficiency bonus.
>
> ***Bardic Inspiration (6/Short Rest).*** Rezmir can use a bonus action on her turn to choose one creature other than herself within 60 feet of her who can hear her. That creature gains one Bardic Inspiration die, a d8.
>
>Once within the next 10 minutes, the creature can roll the die and add the number rolled to one ability check, attack roll, or saving throw it makes. The creature can wait until after it rolls the d20 before deciding to use the Bardic Inspiration die, but must decide before the DM says whether the roll succeeds or fails. Once the Bardic Inspiration die is rolled, it is lost. A creature can have only one Bardic Inspiration die at a time.
>
> ***Spellcasting.*** Rezmir is a 10th-level spellcaster. Her spellcasting ability is Charisma (spell save DC 18, +10 to hit with spell attacks). She has the following bard and paladin spells prepared: 
>
> Cantrips (at-will): *friends, minor illusion, prestidigitation*
>
> 1st-level (4 slots): *absorb elements*‡, *bless, charm person, command, compelled duel, healing word, hold person, longstrider*†, *purify food and drink, shield*‡, *thunderous smite, wrathful smite*
>
> 2nd-level (3 slots): *blindness/deafness, lesser restoration, invisibility, mirror image*†‡
>
> 3rd-level (3 slots): *dispel magic, fear, nondetection*†, 
>
> 4th-level (3 slots): *dimension door, freedom of movement*†
>
> 5th-level (2 slots): *circle of power*‡*, synaptic static*
>
> † *Nondetection* and *mage armor* are automatically cast (she casts the first each morning, and has Rath cast *mage armor* on her). If she expects a fight, she casts *freedom of movement, longstrider,* and *mirror image*. She always keeps a 4th or 5th level slot in reserve in case she needs to *dimension door* away.
>
> ‡ From Magical Secrets
>
>***Divine Smite.*** When Rezmir hits a creature with a melee weapon attack, she can expend one spell slot to deal acid damage to the target, in addition to the weapon's damage. The extra damage is 2d8 for a 1st-level spell slot, plus 1d8 for each spell level higher than 1st, to a maximum of 5d8. The damage increases by 1d8 if the target is a celestial or a metallic dragon or half-dragon.
>
> ### Actions
> ***Multiattack.*** Rezmir makes two attacks. She can apply Divine Smite to one or both of her greatsword attacks, assuming she has the spell slots.
>
> ***Greatsword (Hazirawn).*** *Melee Weapon Attack:* +11 to hit, reach 5 ft., one target. *Hit:* 14 (2d6 + 7) slashing damage plus 7 (2d6) necrotic damage. If the target is a creature, it can’t regain hit points for 1 minute. The target can make a DC 15 Constitution saving throw at the end of each of its turns, ending this effect early on a success.
>
> ***Caustic Bolt.*** *Ranged Spell Attack:* +10 to hit, range 150 ft., one target. *Hit:* 18 (4d8) acid damage, and the bolt creates a 5-foot radius puddle of acid (no damage, but suitable for Acid Step).
>
> ***Acid Breath (Recharge 5-6).*** Rezmir breathes acid in a 30-foot line that is 5 feet wide. Each creature in the line must make a DC 16 Dexterity saving throw, taking 22 (5d8) acid damage on a failed save, or half as much damage on a successful one. It leaves a puddle of acid in the area (no damage, but suitable for Acid Step).
>
> ### Legendary Actions
> If she is wearing the Black Dragon Mask, Rezmir can take up to two legendary actions. Only one legendary action option can be used at a time, and only at the end of another creature’s turn.
>
> ***Darkness.*** A 15-foot radius of magical darkness extends from a point Rezmir can see within 60 feet of her and spreads around corners. The darkness lasts as long as Rezmir maintains concentration, up to 1 minute. A creature with darkvision can’t see through this darkness, and no natural light can illuminate it. If any of the area overlaps with a area of light created by a spell of 2nd level or lower, the spell creating the light is dispelled.
>
> ***Attack.*** Rezmir makes one melee attack.
>
> ***Acid Step.*** When she is standing in acid, Rezmir can teleport up to 60 feet to an unoccupied space she can see that is also coated in acid.
