Actions

Multiattack. Marnek Jaull makes three Boil Blood or Combine Dagger attacks.   Boil Blood. Ranged Spell Attack: +10 to hit, range 60 ft., one target. Hit: 27 ( 5d8+5 ) necrotic damage. The target also takes 11 2d10 fire damage at the start of its next turn. A CON saving throw cancels this ongoing damage, checked at the end of each of the target's turn.   Combine Dagger. Melee Weapon Attack: 1d20+12 to hit, reach 5 ft., one creature. Hit: 15 ( 3d6+5 ) cold damage. The target must succeed on a DC 18 Constitution saving throw or be paralyzed for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. This attack uses Marnek Jail's INT to hit.   Spellcasting. Marnek Jaull casts one of the following spells, using Intelligence as the spellcasting ability (spell save DC 20, 1d20+12 spell attack):

• At will: mage hand, speak with dead, clinging darkness (causes target's shadow to slow and injure target. WIS saving throw or target is slowed (as the spell) and takes 5 1d10 necrotic damage at the start of each of its turn while slowed), shadow step (short-range, random teleportation, otherwise as misty step).
• 2/day each: blight, fear, vampiric curse (target takes 6 ( 1d12 ) necrotic damage each round for 1 minute healing Marnek for the same amount. A CON save at the end of the target's turn to end this effect)
• 1/day: cloudkill, enervation, harmshield (grants Marnek 3 rounds of invulnerability), intensify death* (Marnek's pet who gains 50 temporary hp, does an additional 1d12 necrotic damage on attacks and becomes hasted (as the spell)), reclaim energy (recharge one used spell and he uses it as a bonus action), spirit tap (target takes 44 8d10 necrotic damage to target, and heals for the same amount. Target gains a CON saving throw to half the damage), Toba's acid blast (Marnek chooses two targets within 60 feet of him, each target must make a DEX saving throw or take 5d10+2 acid damage, or half on a success), eternity's torment (5 (1d10) force damage at the start of the target's turn for 1 minute. Target may make an INT saving throw at the end of its turn to end this effect)

Bonus Action

Reactions

Feed on Death (1/Turn). When Marnek kills a creature with necrotic damage, he regains 9 (2d8) hit points.

Legendary Actions

Marnek Jaull can take 3 legendary actions, choosing from the options below. He gains an additional legendary action for every 4 enemies (or part thereof) he is facing beyond the first 4 (i.e. he gains +1 legendary action at 8 enemies, another at 12 and so on). Only one legendary action option can be used at a time and only at the end of another creature’s turn. The lich regains spent legendary actions at the start of its turn.

• Mana Burn. Marnek casts a spell. The spell costs as many actions as uses with "at will" costing 1 action.
• Paralyzing Touch. Marnek uses his Combine Dagger.
• Word of Spirit (Costs 2 Actions). Each non-undead, non-Burning Dead creature within 20 feet of Marnek must make a DC 18 Constitution saving throw against this magic, taking 21 ( 6d6 ) necrotic damage on a failed save, or half as much damage on a successful one.

Lair Actions

When fighting inside his lair, Marnek Jaull can invoke additional effects to take lair actions. On initiative count 20 (losing ties) or when initiative is rolled, Marnek Jaull can take one lair action to cause one of the following effects:

• Disrupt Time. Marnek Jaull sends out a burst of time altering energy throughout the room, affecting all targets other than himself and any allies he chooses. All targets in the room must reroll initiative with disadvantage.
• Alter Time. Marnek Jaull time around a single target within the room. This target's initiative drops by -5 and Marnek Jaull gains +1 initiative.
• Time Turner. Marnek Jaull warps time around two targets within his lair, reducing one target's initiative by -5 and boosting another target's initiative by +5.
