Deadly Illusionist

Your illusions invade the deepest crevice of your enemies’ minds and leave them scarred.

• You add one Illusion spell of a level you can cast, from your class spell list to the list of spells you can prepare or cast. 
• Creatures who fail their initial saving throw or ability check against an Illusion spells of 1st level or higher you cast take psychic damage equal to the spell’s level + your spell casting ability modifier, if the spell does not already deal damage.
