Sight Unseeing is a Technick that causes the target's HP to drop drastically to a random number between 0 and 8. If the ability reduces an opponent's HP to 0, it works basically as an Instant Death attack. Sight Unseeing can only work if the user is blinded and is a great tactic for poaching enemies vulnerable to it. The Technick has initially low base hit chance, but it improves as soon as the user's level is higher than the target's level. The Technick's range is the same as the equipped weapon's.
Sight Unseeing works against any foe that doesn't have the "safety" passive ability. Rare Game, Marks, bosses, elementals and the undead are thus immune, but there are a few areas in the game where the Technick works well. In Subterra the frog- and mistmare-type enemies are weak against the skill and can be killed very fast with Sight Unseeing, a useful tactic as the enemies there are intended to swarm the party.
The license costs 40 License Points.
