Eyes Forward Sparkle alters the sight of the PipBuck users which, when activated, changes the perception of nearby living creatures.
Any nearby life forms of a certain size (criteria unknown) will be assigned a color, either red or yellow. Red life-forms have been identified as hostile by the spell, while yellow indicates neutral or friendly lifeforms. The spell can occasionally identify lifeforms through walls and other solid matter. The only drawback to this is that it doesn't indicate what kind of life form is noted, along with what elevation its located at inside of a building or other multi-level area.
The spell only shows lifeforms in a plane parallel to the ground. Vertical height is not given, which can make it difficult to determine the exact location of the lifeforms in multistory buildings.
In Project Horizons, Blackjack stops blindly relying on her EFS because it can't distinguish frightened scavengers from truly hostile beings; the system is notoriously unreliable for pony interaction in a world where suspicion and hostility are completely justified for survival.
Principle of Operation Edit
Exactly how the spell works continues to baffle Ponies in post-apocalyptic Equestria.
