Multiattack. The illusionist makes two Arcane Burst attacks.
Arcane Burst. Melee or Ranged Spell Attack: +5 to hit, reach 5 ft. or range 120 ft., one target. Hit: 14 (2d10 + 3) psychic damage.
Spellcasting. The illusionist casts one of the following spells, using Intelligence as the spellcasting ability (spell save DC 13):
At will: dancing lights, mage hand, minor illusionDisplacement (Recharge 5–6). The illusionist projects an illusion that makes the illusionist appear to be standing in a place a few inches from its actual location, causing any creature to have disadvantage on attack rolls against the illusionist. The effect lasts for 1 minute, and it ends early if the illusionist takes damage, if it is incapacitated, or if its speed becomes 0.
