Blind Spot

You shift the existance of a willing being you touch so that they are harder to spot. Whenever a creature affected by this spell would be spotted or noticed by another creature looking for them, this creature must make an intelligence saving throw against your spell save DC. If they succeed, they are able to see the affected creature as normal, however, if they fail they do not notice the creature at all, as if they aren't there in the first place. When casting this spell, the creature themselves can choose up to 5 people that can see him normally, without the need to make the saving throw.

If you cast this using a spell slot of 3rd level or higher, you can choose 1 more target of this spell. This continues on for every second spell level.
