SPECIAL TRAITS

• Devil’s Sight. Magical darkness doesn’t impede Xydragis’ darkvision.
• Fear Aura. Any creature hostile to Xydragis that starts its turn within 30 feet of the fiend must make a DC 20 Wisdom saving throw, unless Xydragis is incapacitated. On a failed save, the creature is frightened until the start of its next turn. If a creature’s saving throw is successful, the creature is immune to Xydragis’ Fear Aura for the next 24 hours.
• Innate Spellcasting. Xydragis’ spellcasting ability is Intelligence (spell save DC 20, +12 to hit with spell attacks). It can innately cast the following spells, requiring no material components:
  • At will: bestow curse, detect magic, detect thoughts, magic missile, phantasmal killer, vicious mockery
  • 5/day each: blight, blindness/deafness, confusion, guiding bolt
  • 3/day each: darkness, geas, hold monster
  • 1/day each: blink, feeblemind, harm
• Knowledgeable. Xydragis gains its proficiency bonus (+7) on Intelligence checks.
• Legendary Resistance (3/Day). When Xydragis fails a saving throw, it can choose to succeed instead.
• Magic Weapons. Xydragis’ weapon attacks are magical.
• Metamagic (10 Points/Day). Xydragis can spend metamagic points to activate metamagic when it innately casts a spell, but it can only activate one metamagic per spell.
• Quickened Spell. When Xydragis casts a spell that has a casting time of 1 action, it can spend 2 metamagic points to change the casting time to 1 bonus action for this casting.
