Traits

Innate Spellcasting. Cryptivalus's innate spellcasting ability is Charisma (spell save DC 21). He can innately cast the following spells, requiring no material components:

At will: alter self, animate dead, bestow curse, confusion, major image, modify memory, nondetection, sending, suggestion

3/day each: greater invisibility (self only), mislead

1/day each: feeblemind, symbol (discord or sleep only)

Legendary Resistance (3/Day). If Cryptivalus fails a saving throw, he can choose to succeed instead.

Magic Resistance. Cryptivalus has advantage on saving throws against spells and other magical effects.

Magic Weapons. Cryptivalus’s weapon attacks are magical.

Regeneration. Cryptivalus regains 20 hit points at the start of his turn. If he takes cold or radiant damage, this trait doesn’t function at the start of his next turn. Titivilus dies only if he starts his turn with 0 hit points and doesn’t regenerate.

Ventriloquism. Whenever Cryptivalus speaks, he can choose a point within 60 feet; his voice emanates from that point.

Proof of Work. When Cryptivilus hits a creature with a blockchain attack, he can force that creature to solve a complex cryptogram via brute force. That creature must succeed on a DC 21 Constitution saving throw or begin attempting to solve the problem. While solving the problem, the target is incapacitated. The target can repeat the saving throw at the end of each of its turn, ending the effect on a success. In addition, if the target can cast spells, it can sacrifice any number of spell slots to gain a bonus to the saving throw equal to twice the total spell levels sacrificed.

Speculative Bubble. When a creature successfully solves a crytpogram created by Cryptivalus's Proof of Work feature, it gains a small amount of crypto power to use for itself or pass on to another, represented by a pool of 2d8. When the creature deals damage to another creature, affects it with a spell, or takes the Help action to aid it, the initiating creature can choose to expend the crypto, dealing psychic damage to the target equal to a roll of the current pool, or pass it on, increasing the pool by 1d8 and giving control of it to the target of the effect. 

Actions

Multiattack. Cryptivilus makes three attacks: two with his silver mining pick and one with his blockchain.

Silver Mining Pick. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) piercing damage, or 9 (1d10 + 4) piercing damage if used with two hands, plus 16 (3d10) necrotic damage. If the target is a creature, its hit point maximum is reduced by an amount equal to half the necrotic damage it takes.

Blockchain.Melee Weapon Attack: +9 to hit, reach 20 ft., one target. Hit: 14 (3d6 + 4) bludgeoning damage, plus 16 (3d10) psychic damage. 

Teleport. Cryptivalus magically teleports, along with any equipment he is wearing and carrying, up to 120 feet to an unoccupied space he can see.

Invite to Discord. Cryptivalus targets one creature he can see within 60 feet of him. The target must succeed on a DC 21 Wisdom saving throw or become charmed by Cryptivalus until the end of its next turn. While charmed in this way, the creature worships Cryptivalus as a powerful tech daddy, and must obey Cryptivalus' commands (no action required by Cryptivalus). If the creature fails by 5 or more, it turns to its nearest ally and attempts to spread the gospel of crypto. That creature must succeed on a Wisdom saving throw against a DC of 8 + the speaker's proficiency bonus + their Charisma modifier or also become charmed by Cryptivalus.

Legendary Actions

Cryptivalus 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. Cryptivalus regains spent legendary actions at the start of his turn.

Assault. Cryptivalus attacks with his silver sword.

Blockchain (Costs 2 actions). Cryptivalus attacks with his blockchain

Invite to Discord (Costs 2 actions). Cryptivalus uses Invite to Discord

Teleport. Cryptivalus uses his Teleport action.

Cast a spell. Cryptivalus casts a spell.

Lair and Lair Actions

While in his lair in the Dis Hall of Records, Cryptivalus can take the following lair actions, which occur on initiative count 20, losing ties. Once Cryptivalus uses a lair action, he cannot do so again until he has used at least two other lair actions.

Append Only. Each creature in the lair of Cryptivalus's choice must succeed on a DC 21 Charisma saving throw. On a failure, that target can only take actions affecting the creature immediately following it in initiative. If it cannot affect that creature in any way, it takes the dodge action and ends its turn.

Paper Hands. Each creature of Cryptivalus's choice in the lair must succeed on a DC 21 Strength saving throw. On a failure, the creature's hands temporarily turn to paper until the end of its next turn. A creature with paper hands has disadvantage on weapon attack rolls and unarmed strikes and must succeed on a DC 15 Dexterity check to cast a spell with somatic components. On a failure, the action is wasted but the spell slot is not spent.

Technobabble. Each creature of Cryptivalus's choice in the lair must succeed on the DC 21 Intelligence saving throw or be overwhelmed by a huge quantity of smart-sounding nonsense. While listening to the voices, the target is slowed, as though under the effect of the Slow spell until the end of its next turn.

Bored Ape. Cryptivalus summons an illusory, disinterested ape to fight alongside him. The ape has the statistics of a Giant Ape. A creature can use its action to make a DC 21 Wisdom (Insight) or Intelligence (Investigation) check to determine that the ape is a worthless fraud, dispelling it on a success.

Fork. Cryptivalus can make an additional attack with his blockchain on his next turn.
