Illrigger

Asmodeus is the Lord of Acheron, the City of Fear. His illriggers scour the timescape collecting secrets and spells designed to deceive and terrify his opponents. The war he fights against the other Lords of Hell is one of deception and propaganda.

Acheron's illriggers work to make Hell's enemies seem outnumbered and outmaneuvered. Half their strategy involves research and infiltration, the other half illusion and propaganda. When an Architect of Ruin finally confronts an enemy, the foe sees the illrigger's forces as impossibly powerful, while their own allies betray them and their armies flee in fear.

When you cast an illusion spell, you may choose to expend an unused seal instead of a spell slot.

You have advantage on Constitution saving throws that you make to maintain your concentration on a spell.

When you place a seal on an enemy, you can, as a reaction, cast an illusion spell that normally has a casting time of 1 action.

As a reaction when you cast a spell, you can consume a seal on an interdicted creature to impose disadvantage on their saving throws against the spell.

Your illusion spells no longer require any components. When casting an illusion spell, there is no indication you are casting the spell. You can cast illusion spells while blind, while gagged, and with your hands bound.

You can, as a reaction to taking damage, cast fire shield. The shield is always a warm shield, deals fire damage, and deals 4d8 damage instead of 2d8. You cannot use this feature again until you complete a long rest.

You gain advantage on saving throws against spells and magical effects from interdicted creatures.

As an action, you can become a lore devil for 1 minute. You gain three extra seals. Enemies with seals on them automatically fail their saving throws against your spells. You emanate an interference aura, forcing any creature within 60 feet trying to cast a spell to first succeed at a DC 18 Intelligence saving throw or else the spell fails and they lose the spell slot.

Whenever you use a spell slot to cast a spell, there is a 25% chance the spell works normally but you do not lose the spell slot.

While in this form, your type becomes fiend (devil) and Hell is your home plane. You cannot use this feature again until you complete a long rest. At their discretion, your GM may choose one codex and grant you limited use of one of the abilities from that codex.

Dispater is the Lord of Dis, the City of War. When Hell invades another world, Dispater's army does the fighting and the dying. His Painkillers are master strategists who lead from the front, inspiring terror and awe in their soldiers. They are full of pride and hubris and present themselves as lordly, often having a fastidious obsession with their personal appearance.

The Painkillers are among the most chivalrous of the illriggers, but theirs is a twisted chivalry. They will accept and honor a challenge to single combat, and swiftly punish any who try to interfere. But they will cheat if losing and toy with an enemy before finishing them if winning.

In a moment of weakness or desperation, a ruler in another World might see their army facing certain defeat and call upon Dispater. Seeing the opportunity to sow strife and discord, Dispater might send a Painkiller to lead the desperate lord's armies.

After placing a seal on a creature, your attacks against that creature have advantage until the end of your turn.

You can, as an action, place a seal on an enemy within 30 feet. If they are Large or smaller, they must make a Wisdom saving throw (DC = 8 + your Proficiency bonus + your Charisma modifier) or be grappled (escape DC 15), and the target is restrained until the grapple ends.

You can, as a reaction to an enemy moving into a space adjacent to you, place a seal on them. If you do, they must make a Wisdom saving throw (DC = 8 + your proficiency bonus + your Charisma modifier). If they fail, they are thrown back 30 feet and knocked prone.

The bonus action you use to place a seal on a creature now also grants you a weapon attack against them.

When an ally within 30 feet who can hear you drops to 0 hit points but is not outright killed, you can use your reaction to shout an order at them, causing them to drop to 1 hit point instead. You cannot use this feature again until you complete a short or long rest.

You gain advantage on Wisdom saving throws against spells and enemy abilities.

When you consume a seal after a successful attack roll against an interdicted creature, you may use your reaction to make the attack score a critical hit.

Starting at 20th level, you can use your action to become a pain devil for 1 minute. Your size becomes Large. You gain +3 to hit and damage with melee weapons. You gain 100 temporary hit points.

You emanate an aura of pain that forces every enemy starting their turn within 20 feet of you to make a DC 16 Constitution saving throw or suffer 4d12 force damage on a failed save (half that on a successful saving throw) as wounds in their flesh spontaneously open. Once a creature saves, they are immune to this ability for 24 hours.

While in this form, your type becomes fiend (devil) and Hell is your home plane. You cannot use this feature again until you complete a long rest.

Moloch is the Lord of Styx, the City of Lies. He strives to rule Hell through subterfuge, deceit, and trickery. His illriggers are assassins, striking from the shadows or using deception to earn high-ranking positions close to powerful rulers. Many Shadowmasters run networks of spies and assassins who have no idea of the infernal provenance of their master.

The Shadowmasters are sworn not to reveal themselves and to take their own lives before betraying their true allegiance. Many Shadowmasters have elaborate plans ready for their own assassination so that, should someone get close to discovering their true identity, they will be killed by their own assassins, preserving the truth. Of course, these killers have no idea who they were really working for...

Your connection to Moloch's power deepens. If you hit an interdicted creature with a melee attack, you can mark them for death. The target has disadvantage on attack rolls that do not include you until the end of its next turn. While that creature is interdicted, it must make a Wisdom saving throw (DC equal to 8 + your proficiency bonus + your Charisma modifier) whenever it tries to leave your reach. On a failure, its speed instead becomes 0 until the start of its next turn. These effects last until it is no longer interdicted, you leave its reach, or it leaves your reach.

Your movement increases by 10 feet.

Your mastery of shadow grants you advantage on Dexterity (Stealth) checks when taking the Hide action, and Hide becomes a bonus action for you..

While within 10 feet of an interdicted enemy, shadows envelop you and you gain the benefits of half cover.

When you are prompted to make a Dexterity saving throw to take only half damage from an effect, you instead take no damage if you succeed on the saving throw, and only half damage if you fail.

You gain darkvision and can see normally in magical darkness. In addition you can see the exact location of any creatures within 60 feet using illusion spells to obfuscate their location, such as blur, mirror image, or invisibility.

Your seals do 3d10 damage each, rather than 3d6.

Starting at 20th level, as an action, you can become a greater shadow for 1 minute. You gain damage resistance to acid, cold, fire, lightning, thunder, bludgeoning, piercing, and slashing damage. You gain Incorporeal Movement and a flying speed of 50 feet. You can move through other creatures and objects as if they were difficult terrain. You take 5 (1d10) force damage if you end your turn inside an object. Your weapon attacks deal necrotic damage, and successful attacks drain 1d4 Strength from the target. If this drain reduces the target's Strength to 0, it dies. Otherwise, the drain lasts until the target finishes a short or long rest. If a non-evil humanoid dies from this attack, a new shadow rises from the corpse 1d4 hours later. You cannot use this feature again until you complete a long rest.
