Vision penetration

You touch your fingertips to your eyelids then point at a creature of your choice. If they are willing the spell works, but if not, they must succeed on a WIS saving throw or you will see through their eyes without their knowledge. If the saving throw is passed you can see through their eyes but the spell only lasts ten rounds of combat (60 seconds).

The spell doesn't hinder the target's own ability to see. The caster has access to the target's vision but doesn't benefit from any sensory benefits that the target benefits from (e.g. darkvision).

Any creature nearby the target can make an investigation check against your spell save DC to notice that the spell is affecting the target, the colour of your eyes appear in the target's. If the target becomes aware of the spell's effect on them then they can make a WIS save every minute in order to resist its effects. If the WIS save is failed then the creature is blinded for 1 round of combat.
