Bronze Dracolich Calcium Stealer

Legendary Resistance (3/Day).  If the dragon fails a saving throw, it can choose to succeed instead.

Calcium Stealer.  The stolen calcium from creatures empowers the dracolich while weakening his enemies. If the dracolich has recently stolen calcium, his melee attacks will gain a +7 to their respective damage type added, as well as regain 3d8 Hit Points.

Skeletal Fragility.  Creatures that are afflicted with the fragility of their skeletal tissue, have a -3 to hit on their attacks and disadvantage on ability checks until they consume a healing potion, recieve magical healing of 2nd level or higher, or take a long rest. These effects do not stack more than once.

Multiattack. The dragon can use its Frightful Presence. It then makes three attacks: one with its bite and two with its claws.

Bite. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 18 (2d10 + 7) piercing damage. If empowered with calcium, Hit: 25 (2d10 + 14) piercing damage.

Claw. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 14 (2d6 + 7) slashing damage. If empowered with calcium, Hit: 21 (2d6 + 14) slashing damage.

Tail. Melee Weapon Attack: +12 to hit, reach 15 ft., one target. Hit: 16 (2d8 + 7) bludgeoning damage. If empowered with calcium, Hit: 23 (2d8 + 14) bludgeoning damage.

Frightful Presence. Each creature of the dracolich's choice that is within 120 feet of the dragon and aware of it must succeed on a DC 17 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the dracolich's Frightful Presence for the next 24 hours.

Calcium Absorbtion Beam (Recharge 4–6).  The dragon inhales and creatures in a 40- foot cone in front of the dracolich must make a DC 16 Dexterity saving throw or DC 17 Constitution saving throw, taking 42 (6d10) calcium damage. If the creature succeeds the saving throw, it resists the Skeletal Fragility status effect and takes only half the original calcium damage.

The dracolich can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. The dracolich regains spent legendary actions at the start of its turn.

Detect. The dracolich makes a Wisdom (Perception) check.

Tail Attack. The dracolich makes a tail attack.

Wing Attack (Costs 2 Actions). The dracolich beats its tattered wings. Each creature within 10 ft. of the dracolich must succeed on a DC 19 Dexterity saving throw or take 14 (2d6 + 7) bludgeoning damage and be knocked prone. The dragon can then fly up to half its flying speed.
