Level 2
Quiet Casting
All spells you cast from any school of magic are silent to others.
Hypnotic Gaze
Your soft words and enchanting gaze can magically enthrall another creature. As an attack action, choose one creature that you can see within 1 unit ring of you. If the target can see or hear you, it must succeed on a sense saving throw against your wizard spell save DC or be charmed by you until the end of your next turn. The charmed creature's movement drops to 0, and the creature is incapacitated and visibly dazed. On subsequent turns, you can use your attack action to maintain this effect, extending its duration until the end of your next turn. However, the effect ends if you move away from range from the creature, if the creature can neither see nor hear you, or if the creature takes damage. Once the effect ends, or if the creature succeeds on its initial saving throw against this effect, you can't use this feature on that creature again until you finish a long rest.
Level 6
Hypnotic Lullaby
The reach of your Hypnotic Gaze is now a 6-unit ring around you, and it ends if you move away from the range.
Master of the Mind
Illusion spells work on undead.
Level 9
Mass Control
You can attempt to hypnotize everyone within range of your Hypnotic Gaze.
Split
When you cast an illusion spell that targets only one creature, you can have it target a second creature.
