I converted Iuz the old, Demigod of pain and oppression to 5e. So I want to share my work. I marked him down at CR 25 but I have not actually gone through the DMG steps of determining what his actual CR is, so 25 is a place holder for now.

Traits
Cloak of Protection +3: Iuz gains a +3 bonus to AC and saving throws while he wears this cloak.
Discorporation: When Iuz drops to 0 hit points, or dies his essence travels to his soul gem in layer 222 of the Abyss and can’t take physical form for a time. If the gem has been destroyed, his essence goes to his domain on Oerth on the material plane instead unless he was slain there in which case he truly dies.
Innate Spellcasting Iuz’s innate spellcasting ability is Charisma (spell save DC 19, +12 to hit with spell attacks). He can innately cast the following spells, requiring no material components:
At will: finger of death, invisibility, phantasmal force, protection from good and evil, teleport, wall of force.
2/day: dispel evil and good, dispel magic, raise dead
1/day: anti-magic field, gate, harm, wish, symbol.
Magic Weapons: Iuz’s attacks count as magical weapons.
Legendary Resistance (3/day): If Iuz fails a saving throw he can choose to succeed instead.
Limited Magic Immunity: Iuz is immune to spells of 6th level or lower unless he wishes to be affected. He has advantage on saving throws against all other spells and magical effects.
Shapechanger: Iuz can appear as a medium sized old man or as a large or huge demonic cambion in golden and black plate armor. In his old man form, Iuz can use his spittle and claws. In his cambion form he can use his +3 huge greatsword and plate armor. Other statistics other than size remain the same no matter his form.
Spellcasting Iuz is a 16th-level spellcaster. His spellcasting ability is Wisdom (spell save DC 20, +13 to hit with spell attacks). Iuz has the following Cleric spells prepared:
Cantrips (at will): guidance, mending, resistance, spare the dying, thaumaturgy
1st level (4 slots): bane, cure wounds, false life, ray of sickness
2nd level (3 slots): augury, blindness/deafness, lesser restoration, ray of enfeeblement,
3rd level (3 slots): animate dead, bestow curse, dispel magic, sending, tongues, vampiric touch
4th level (3 slots): banishment, blight, death ward, freedom of movement
5th level (2 slots): antilife shell, cloudkill, contagion, insect plague, mass cure wounds, planer binding, scrying
6th level (1 slot): create undead, heal, planer ally
7th level (1 slot): resurrection, plane shift
8th level (1 slot): control weather
Actions
Multiattack: Iuz attacks twice with his claws and once with his spittle in old man form or twice with his greatsword in cambion form.
Claw. Melee Weapon Attack: +13 to hit, reach 5 ft., one target. Hit: (1d4+5) slashing damage. If Iuz hits with both claws and his target is a medium seized creature with a neck, he grapples and restrains his target and starts to strangle them. (Escape dc 21) A creature being strangled counts as being suffocated and can survive for a number of rounds equal to its Constitution modifier (minimum 1 round). At the start of its next turn, it drops to 0 hit points and is dying. Iuz can’t use his claws again until the grapple ends.
Spittle (1/round). Ranged Weapon Attack: +12 to hit, range 10 ft., one creature .Hit: The target is aged 1d6 years. Furthermore, the body part struck becomes numb and is useless for 1d4+ 1 rounds (roll 1d12: 1=head, 2/3=right arm, 4/5=left arm, 6/7=right leg, 8/9=left leg, 10/12=torso.) A torso hit makes a character collapse prone in pain, remaining conscious but unable to perform actions. A hit to the head brings unconsciousness. Has no effect on constructs, elementals, oozes and undead.
+3 Greatsword (Cambion form only). Melee Weapon Attack: +16 to hit, reach 10 ft., one target: Hit: [6d6+8] slashing damage.

Iuz 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. Iuz regains spent legendary actions at the start of his turn.
Attack. Iuz makes one of his attacks. If Spittle has been used earlier in the round it can’t be used again this round.
Move. Iuz moves up to half his speed.
