Preparing and Casting Spells

The illrigger table shows how many spell slots you have to cast your spells. To cast one of your illrigger spells of 1st level or higher, you must expend a slot of the spell’s level or higher. You regain all expended spell slots when you finish a long rest.
You prepare the list of illrigger spells that are available for you to cast, choosing from the illrigger spell list. When you do so, choose a number of illrigger spells equal to your Charisma modifier + half your illrigger level, rounded down (minimum of one spell). The spells must be of a level for which you have spell slots.
For example, if you are a 5th-level illrigger, you have four 1st-level and two 2nd-level spell slots. With a Charisma of 14, your list of prepared spells can include four spells of 1st or 2nd level, in any combination. If you prepare the 1st-level spell hell’s lash, you can cast it using a 1st-level or a 2nd-level slot.
Casting the spell doesn’t remove it from your list of prepared spells. You can change your list of prepared spells when you finish a long rest. Preparing a new list of illrigger spells requires time spent in prayer and meditation: at least 1 minute per spell level for each spell on your list.

 

Spellcasting Ability

Charisma is your spellcasting ability for your illrigger spells, since their power derives from your ability to command the attention of your patron archdevil. You use your Charisma whenever a spell refers to your spellcasting ability. In addition, you use your Charisma modifier when setting the saving throw DC for an illrigger spell you cast and when making an attack roll with one.
Spell Save DC = 8 + your proficiency bonus + your Charisma modifier
Spell attack modifier = your proficiency bonus + our Charisma modifier

At 1st level, you gain proficiency in your choice of two of the following skills: Deception, Insight, Intimidation, or Persuasion.
Your proficiency bonus is doubled for any ability check you make that uses either of those skills.

 

Infernal Conduit

There is a well of infernal power within you that replenishes after you take a long rest. With this well, you can transfer hit points between yourself and other creatures. You can transfer a number of hit points equal to your illrigger level x 4.
As an action, you can touch a willing creature to either heal yourself by dealing necrotic damage to that creature or heal the creature by dealing necrotic damage to yourself. You can draw a number of hit points to transfer in this way from your pool, up to the maximum amount remaining in your pool.
You can also target an unwilling creature. When you do so, the target must make a Constitution save. On a success, they are unaffected and immune to this feature for the next 24 hours. On a failure, the creature is affected as though they were willing.
If you are at maximum hit points and drain hit points from a creature, you gain temporary hit points equal to the amount you drained. You can not give another creature temporary hit points in this way.
At 9th level, you can choose to remove a first level spellslot from a creature by expending 8 hitpoints from your pool. Alternatively, you may restore a creatures spellslots in the same manner, spending 8 hitpoints from your pool. This creature can be yourself.
At 13th level, when a creature is affected by your infernal conduit, you learn the emotional state and surface level thoughts of the creature. Additionally, you have advantage on Wisdom (Insight) checks made against the creature for the next hour.

 

Underhanded Technique

At 2nd level, you adopt a deceptive style of fighting as your specialty. Choose one of the following options. You can't take an Underhanded Technique option more than once, even if you later get to choose again.

Bravado

While you are not wearing any armor, your Armor Class equals 10 + your Dexterity modifier + your Charisma modifier. You can use a shield and still gain this benefit.

Lies

While wielding a melee weapon with two hands, you may choose to use your Strength or Charisma modifier for the attack and damage rolls.

Schemes

While you wield a melee weapon in one hand and no other weapons, you may use your reaction to attack an adjacent enemy who hits you with a melee weapon attack.

Treachery

Your melee weapon attacks deal an extra 1d6 damage when an ally creature is within 5 feet of your target.  

Spellcasting

At 2nd level, you gain the ability to cast spells. (See Spellcasting)  

Baleful Interdict

Upon reaching 2nd level, you learn to use the power granted by your Archdevil to censure other creatures. As a bonus action, you can expend a spell slot to place a seal on a target within 30 feet of you.
When you or an ally hit a sealed creature with a weapon attack, you can consume the seal to deal necrotic damage to the target, in addition to the weapon's damage. This extra damage is 2d6 for a 1st-level spell, plus 1d6 for each spell-level higher than 1st, to a maximum of 5d6. The damage increases by 1d6 if the target is a celestial or fiend, to a maximum of 6d6. If you are within 30 feet of the creature when you consume your seal, you regain a hit point for each die of damage your seal inflicts.
Your seal evaporates after one minute, if not consumed. Only the illrigger who placed the seal knows it’s there, it appears in the illrigger’s sight as a glowing glyph on the creature’s forehead.

 

Hellsight

Starting at 3rd level, you have advantage on Wisdom (Perception) checks to notice disguised, hidden, or invisible creatures.

 

Knight of Hell

Also at 3rd level you pledge your soul to the service of an archdevil and are welcomed into the Order of Desolation, becoming an illrigger. You gain the Invoke Authority feature and choose either Shadowmaster , Painkiller or Architect of Ruin , all detailed at the end of the class description.
Furthermore, you are a noble in the lists of Hell and will be accorded fine treatment and hospitality anywhere in hell you travel, even to cities ruled by enemy Archdevils. More cosmopolitan cities in the timescape--like Alloy, the City of Brass--will also respect your noble rank.

 

Authority Spells

Each of the Lords of Hell grant different spells to their elite death commandos. You gain access to these spells at the levels specified in the Invoke Authority description. Once you gain access to an oath spell, you always have it prepared. Authority spells don’t count against the number of spells you can prepare each day.
If you gain an authority spell that doesn’t appear on the illrigger spell list, the spell is nonetheless an illrigger spell for you.

 

Invoke Authority

You invoke the authority granted you by your Archdevil lord, channelling baleful energy to fuel magical effects. Each Invoke Authority option provided by your Archdevil explains how to use it.
When you use your Invoke Authority, you choose which option to use. You must then finish a short or long rest to use your Invoke Authority again. Some Invoke Authority effects require saving throws. When you use such an effect from this class, the DC equals your illrigger spell save DC.

 

Ability Score Improvement

When you reach 4th level, and again at 8th, 12th, 16th, and 19th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can't increase an ability score above 20 using this feature.

 

Extra Attack

Beginning at 5th level, you can attack twice, instead of once, whenever you take the Attack action on your turn.

 

Marquis of Hell

Starting at 6th level, you can exert your hellish authority over celestials and fiends. Using your action, you can choose a celestial or fiend within 30 feet of you and force it to make a Charisma saving throw against your illrigger spell save DC. On a failure, the target is charmed by for the next hour. While charmed in this way, the target regards you as a friendly acquaintance as though they were affected by a charm monster spell. Once you target a creature with this feature, it is immune to it for the next 24 hours.
At 18th level, your hellish authority allows you to command the creature to obey you completely. On a failure, the target is dominated as though they were affected by the dominant monster spell.

 

Duke of Hell

Upon reaching 10th level, you gain the ability to summon a Barbed Devil to serve you for one hour. Doing so uses your action and can only be done once a week. The Devil is bound to you and must obey your commands to the best of its ability. It acts on the same initiative as you, and may both act and move on the turn you summon it. If you die or fall unconscious, the devil returns to Hell.

You take 5 (1d10) force damage if you end your turn inside an object. Your weapon attacks deal necrotic damage and successful attack drain 1d4 strength from the target. The target dies if this reduces its Strength to 0. Otherwise, the reduction lasts until the target finishes a short or long rest.
