Song of Sight

1-point divination (prophecy)
Casting time:	action
Range:	30 feet
Components:	V, S, M (a musical instrument)
Duration:	concentration, up to 10 minutes

Your smooth instrumental melody sharpens the senses of those who hear it. While this spell persists, friendly creatures in range who can hear you have advantage on all sight-based Wisdom (Perception) checks and Intelligence (Investigation) checks. Additionally, you and all affected creatures can clearly see otherwise invisible objects and creatures.
 Upcast. You can upcast this spell by expending extra spell points when you cast it. For each extra point, increase the range by 10 feet.
