Vistana Illusionist

You have inherited some innate sorcery from your maternal bloodline. This ability bolsters your ability to cast illusions, you gain one mirage die per spellcasting level, it's value is d6. You gain the ability to attack illusions to creatures, or centre them on a single point. 

When you cast an illusion spell, you can spend a mirage die, then choose one creature that has seen the illusion and force it to make an intelligence saving throw versus your spellcasting (DC), becoming tricked on a failure.

While a creature is 'tricked', a telepathic link is opened, the target is either blinded or deafened (depending on the illusion) for the duration of the illusion spell. 

Your mirage die replenish after a long rest.
