This is for 5e.

Hey all. I want to turn a very weakened version of Mind Flayer's Mind Blast into a level 1 Wizard spell. I have a good idea of what it should look like, but I don't trust myself when it comes to balance and would appreciate some help. I want it to do damage in an area and add a short effect.

This is what I've come up with so far (based on Burning Hands)

Mini Mind Blast
School: Enchantment
Level: 1
Components: V, S
Casting Time: 1 Action
Range: Self (15-foot cone)
Duration: Instantaneous
Saving Throw: Int; If successful - no damage and no effect
Damage: 2d6 psychic
Additional Effect: This is the hardest part. I was thinking either Disadvantage on attacks for 1 round or no Reaction for 1 round or no movement for 1 round. Or maybe some combination of those.

What do you think?
Any interesting ideas that would break this format are also welcome as long as they still feel like a smaller mind blast and are level 1.

Interesting idea. However, as it isn't a cantrip, I suggest at least allowing half damage on a successful save. The riders you've suggested would work, but I feel like cantrips all cover those niches. Instead, try something new. I suggest: Disrupt Equilibrium. On a failed save, targets' sense of balance is ruined. Until the end of their next turn, they must make a Dexterity Saving Throw for every 10ft they move (including forced movement), or else fall prone and end their turn. For extra lulz, consider stipulating that on a roll of 1 against the movement effect, the vertigo is so severe that they vomit, and are poisoned for 1 turn after.
