Scan enemy's HP and weakness
Scan is a magic spell in Final Fantasy VIII that reveals information about the target, including stats and weaknesses. It can also be junctioned to boost stats, though it is the poorest spell for this purpose. The player can scan both enemies and party members.
Scan is one of the few spells that cannot be refined from items and must be drawn; the only others being Float and Apocalypse. There are few enemies from which Scan can be drawn, who are found near the start of the game.
Scan displays the target's stats that can be used on both enemies and party members. If an enemy's HP exceeds 99,999, its HP is displayed as ????? until it falls below 99,999. Scan has two animations that can be altered in the config section of the menu. It can be cast on enemies or teammates to rotate them 360 degrees, except for Selphie (likely for decency reasons).
Because enemies in Final Fantasy VIII have variable HP based on the player's level, and because the junction system allows the player to take advantage of enemies' elemental weaknesses, Scan can be useful when cast as a spell in many instances. The spell only provides very minor boosts to stats when junctioned, meaning it is better used for casting with Magic than for junctioning to stats. Blobras spawn with a random elemental weakness, resisting everything else, making Scan especially useful against them. Thus, it can be a good ides to stock up on Scans in the starting area before moving on to Timber, as enemies who have Scan don't appear much later on.
