  • Devil’s Sight. Magical darkness doesn’t impede the devil’s darkvision.
  • Magic Resistance. The devil has advantage on saving throws against spells and other magical effects.
  • Technomagical Susceptibility. Any effect that works on a construct works on a lislaroth. An effect that works on a construct and a fiend has the worst possible effect.
  • Universal Interface. The lislaroth is proficient with computers and adds double (+6) its proficiency bonus (+3) to all computer-related checks. The lislaroth can use a computer within 40 feet as though it had physical access to it.


  • Electrical Discharge. Ranged Weapon Attack: +4 to hit, range 40/120 ft., one target. Hit: 19 (4d8 + 1) lightning damage.
  • Claw. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 8 (2d6 + 1) slashing damage.
  • Command Construct. The lislaroth can issue a command to a nearby construct. This works like the spell command but affects only constructs, with a Wisdom DC of 18.
  • Destruction Protocol (Recharges 5-6). Melee Spell Attack: +8 to hit, reach 5 ft., one target construct. Hit: The construct must make a DC 18 Intelligence saving throw. On a failed save, the target attacks a creature of the lisraloth’s choosing each round, using the Attack or Multiattack action if available. If the lisraloth is unconscious or does not issue commands, the target randomly attacks the nearest creatures. At the end of each of the target’s turns, it may make a new saving throw, ending the effect on a success.


Hacker devils, called lislaroth in Infernal, are Hell’s digital spies. They have a generally humanoid form, with pale skin and glowing red eyes, but their bodies are a hybrid of withered flesh and cybernetic parts. Portions of their limbs are entirely mechanical, and even the classic diabolic horns are themselves made of metal spines and protrusions, shot through with wires and often many tiny blinking lights. They can interface with other machines and especially with linked computer networks and sentient artificial intelligences to gain access to sensitive data, which they use or trade to corrupt mortal souls. A hacker devil stands 6 feet tall and weighs 170 pounds.
