Zarqonel

Multiattack. Zarqonel makes two Slam attacks. If its Eye Beam is recharged, it can replace one Slam with Eye Beam.

Slam. Melee Weapon Attack: +12 to hit, reach 15 ft., one target. Hit: 27 (4d10 + 6) bludgeoning damage. If the target is a creature, it must succeed on a DC 19 Strength saving throw or be knocked prone.

Eye Beam (Recharge 5-6). Ranged Spell Attack: +11 to hit, range 300 ft., one target. Hit: 63 (14d8) radiant damage, and the target is dazed—on its next turn it can take only the Dash, Disengage, or Dodge action unless it succeeds on a DC 19 Wisdom saving throw at the end of that turn.

Crystal Heart (Recharge 6). Zarqonel fractures the blue chest crystal, unleashing a 90-foot cone of ripping arcana. Each creature in that cone must make a DC 19 Dexterity saving throw. A failed save takes 91 (14d12) force damage and is stunned for 1 minute; a successful save takes half as much damage and is not stunned. A creature stunned by this effect can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. After using this action, the crystal shatters and Zarqonel cannot use Crystal Heart again until it spends 1 minute reknitting the crystal (during which it is vulnerable to radiant damage).

Soul Siphon (Recharge 6). Zarqonel forces the chest crystal to draw a creature’s essence. One creature Zarqonel can see within 60 feet must succeed on a DC 19 Charisma saving throw or have its hit point maximum reduced by 40 (8d8 + 4). Zarqonel regains hit points equal to the amount reduced. The reduction lasts until the creature finishes a long rest or until the crystal is destroyed.

Reflective Aegis. When Zarqonel is targeted by a magic missile or a ranged spell attack, it can impose disadvantage on the attack roll and gain resistance to that spell’s damage. If the spell deals no damage, the attacker suffers 21 (6d6) radiant backlash damage instead (no save).

Slam. Zarqonel makes one Slam attack.

Eye Flicker (Costs 2 Actions). Zarqonel fires a condensed Eye Beam at one creature within 120 feet. Ranged Spell Attack: +11 to hit. Hit: 22 (5d8) radiant damage, and the target must succeed on a DC 19 Wisdom saving throw or have disadvantage on attack rolls until the end of its next turn.

Thunderous Step (Costs 3 Actions). Zarqonel stomps. Each creature within 30 feet must succeed on a DC 19 Strength saving throw or be knocked prone and take 27 (6d8) bludgeoning damage on a failed save, or half as much damage and not be knocked prone on a successful one. Structures and unattended objects in the area take double damage.
