Subclass Illrigger Hellspeaker
The Hellspeaker is an Illrigger subclass built around the Charmed condition. Its seals charm the creatures they mark, its attacks against Charmed creatures gain automatic Advantage, a limited once-per-Short-Rest Reaction can force a guaranteed critical hit, and its Level 11 feature briefly weakens a freshly-sealed creature's mental saving throws.
| LEVEL | FEATURE |
|---|---|
| 3 | Moloch's Blessing, Charm Enemy, Honey-Sweet Blades |
| 7 | Intransigent |
| 11 | Incontrovertible |
You gain Expertise in Persuasion and Deception checks.
Both skills are fueled by Charisma — every out-of-combat negotiation, interrogation, or deception benefits without splitting stat investment.
When you use your Bonus Action to place a seal on a creature, you can Charm it for 10 turns.
Charm Enemy converts Baleful Interdict into a Charm setup: the seal you were placing anyway now also neutralizes the target. A Charmed creature can't attack you, and it becomes the ideal target for Honey-Sweet Blades.
Weapon attacks against a Charmed creature automatically gain Advantage on the attack roll — this part is passive and always on.
Turning a hit into a Critical Hit is a separate, limited Reaction, not an automatic upgrade: after your roll against a Charmed target, you can spend a Reaction plus your one Honey-Sweet Blades charge to set that roll to a natural 20. This charge is capped at once per Short Rest — you can't do this on every hit, only once between rests.
The loop: place a seal (Bonus Action) → the target is Charmed → attack it with automatic Advantage → once per Short Rest, spend the Reaction to force a natural-20 result on one of those hits. Save the guaranteed crit for the swing that matters most, since you only get it once per Short Rest.
You are immune to the Charmed condition. You also have a passive minimum-roll floor of 10 on qualifying ability checks and skill checks, and on any saving throw that uses Charisma — this is always on and does not cost a seal or any other resource, unlike what a "expend a seal" framing might suggest.
Intransigent makes the Hellspeaker immune to the condition it inflicts, and puts a reliability floor under its checks and Charisma saves, for free.
The moment you place a new seal on a creature, it also gains Disadvantage on Wisdom and Charisma saving throws for 2 turns. This is a one-time burst triggered by the act of sealing, not a continuous effect that lasts for as long as the seal itself persists — placing a fresh seal is what re-triggers the 2-turn window.
Incontrovertible makes each fresh seal placement a debuff platform for the whole party: any spellcaster targeting Wisdom or Charisma saves (Hold Person, Fear, Command, Banishment) gets Disadvantage on the marked target for those 2 turns, so time your party's saves-based spells to follow right after you place a seal.
The Hellspeaker is a Charm-loop striker that neutralizes a priority target and then leans on Advantage, with one guaranteed critical available per Short Rest.
Your combat identity:
- Baleful Interdict + Charm Enemy — place a seal as a Bonus Action; the target is Charmed for 10 turns
- Honey-Sweet Blades — attack the Charmed target with automatic Advantage; once per Short Rest, spend the Reaction to force a natural-20 hit
- Burn seals on the forced crit — seal damage dice benefit from the Critical Hit as well, so line it up with your one guaranteed critical
- Intransigent at Level 7 — you cannot be Charmed back, and your checks/Charisma saves have a free floor of 10
- Incontrovertible at Level 11 — placing a fresh seal gives that target Disadvantage on Wisdom and Charisma saves for 2 turns; coordinate with party casters to land their save-based spells in that window
