Echo Shield

When the player casts this spell, it creates a translucent disc of protective energy the size of a shield. While wielded in such a way, the shield grants a +1 to AC. The caster is considered proficient with the shield as a weapon, which deals 1d4 dmg, and has the light and thrown properties, with a range of 20/40 ft. If the shield is thrown as a weapon, it dissipates, ending the spell

Additionally, the caster may use the shield as a scouting device. If thrown in any direction without attacking an opponent, the shield dissipates, but grants advantage to Perception checks for 1 round.

At higher levels, this spell deals additional damage.
