"One of the eight status ailments in the game, Silence is attempted to be inflicted by a couple of attacks, such as the Mage's Muffle. Regardless of resistance or lack thereof, it never seems to get set. Nevertheless, the status does exist, complete with accompanying effects. It was probably removed on purpose to make the game easier or it was a bug/programming error."
This patch completely restores all silence status functionality, making the game a little more challenging. If the spell catches, your character will be unable to use spells, both in battle and out of battle. To heal status, use a Heal Potion or Heal spell with another character.
Enjoy! And be careful not to be silenced hehe...
