Actions

Multiattack. Gynok can use his Dreadful Glare and makes two attacks: one with his Rotting Fist and another with his Sickening Rapier.   Rotting Fist. Melee Weapon Attack: 1d20+9 to hit, reach 5ft, one target. Hit: 14 ( 3d6+4 ) bludgeoning damage plus 21 ( 6d6 ) necrotic damage. If the target is a creature, it must succeed on a DC 16 Constitution saving throw or be cursed with mummy rot. The cursed target can’t regain hit points, and its hit point maximum decreases by 10 (3d6) for every 24 hours that elapse. If the curse reduces the target’s hit point maximum to 0, the target dies, and its body turns to dust. The curse lasts until removed by the remove curse spell or other magic.   Sickening Rapier. Melee Weapon Attack: 1d20+9 to hit, reach 5ft, one target. Hit: 8 ( 1d8+4 ) piercing damage, and the target must make a DC 16 Constitution saving throw, taking 24 ( 7d6 ) poison damage on a failed save and is poisoned for 1 minute, or half as much damage on a successful one and not poisoned. While a creature is poisoned it takes 1d10 poison damage at the start of each of its turns. The target can repeat the saving throw at the end of its turn to end the poison condition. This weapon scores a critical hit on a 15-20 and does 54 damage (12 piercing, and 42 poison damage). If the attack is a sneak attack the total damage is 102.   Dreadful Glare. Gynok targets one creature he can see within 60 feet of him. If the target can see the mummy, it must succeed on a DC 16 Wisdom saving throw against this magic or become frightened until the end of Gynok’s next turn. if the target fails the saving throw by 5 or more, it is also paralyzed for the same duration. A target that succeeds on the saving throw is immune to the dreadful glare of all mummies and mummy lords for the next 24 hours.

Legendary Actions

Gynok can take 3 legendary actions, choosing from the options below. Gynok gains an extra legendary action for every 4 PCs after the first 4 (i.e. +1 at 8, another +1 at 12 etc.) Only one legendary action option can be used at a time and only at the end of another creature’s turn. Gynok regains spent legendary actions at the start of its turn.

• Attack. Gynok makes one attack with his rotting fist or uses his dreadful glare.
• Blinding dust. Blinding dust and sand swirls magically around Gynok. Each creature within 5 feet of Gynok must succeed on a DC 16 Constitution saving throw or be blinded until the end of the creature’s next turn.
• Blasphemous word (costs 2 actions). Gynok utters a blasphemous word. Each non-undead creature within 10 feet of Gynok that can hear the magical utterance must succeed on a DC 16 Constitution saving throw or be stunned until the end of Gynok’s next turn.
• Channel negative energy (costs 2 actions). Gynok magically unleashes negative energy. Creatures within 60 feet of Gynok, including ones behind barriers and around corners, can’t regain hit points until the end of Gynok’s next turn.
• Whirlwind of sand (costs 2 actions). Gynok magically transforms into a whirlwind of sand, moves up to 60 feet, and reverts to his normal form. While in whirlwind form, Gynok is immune to all damage, and he can’t be grappled, petrified, knocked prone, restrained, or stunned. Equipment worn or carried by Gynok remain in his possession.

Lair Actions

On initiative count 20 (losing initiative ties), Gynok takes a lair action to cause one of the following effects; he can’t use the same effect two rounds in a row.

• Each undead creature in the lair can pinpoint the location of each living creature within 120 feet of it until initiative count 20 on the next round.
• Each undead in the lair has advantage on saving throws against effects that turn undead until initiative count 20 on the next round.
• Until initiative count 20 on the next round, any non-undead creature that tries to cast a spell of 4th level or lower in Gynok's is wracked with pain. The creature can choose another action, but if he tries to cast the spell, he must make a DC 16 Constitution saving throw. On a failed save, he takes (1d6) necrotic damage per level of the spell, and the spell has no effect and is wasted.

Gynok is trapped in Befallen and confined to the old Fists of Marr's Trophy Room. If Gynok is encountered in his lair (the Trophy Room), he has a challenge rating of 16 (15,000 XP).
