Illusionary Vision

For the duration, you see through any illusion, which allows you to see things for what they are without the effect of the illusion, you are not aware that there is an illusion effect present you just simply see through it - for example if there is a creature in front of you which is invisible, you see the creature but you are unaware that it is invisible to everyone else unless you know about through other means (like someone telling you they can't see that creature).

At higher levels. If you cast this spell using a 3rd level spell slot the duration is an hour, if you cast this spell using a 4th level or higher you can bestow this effect to two creatures yourself and another willing creature. For every level above 4th you can bestow this effect to one additional creature.
